[0002] In the process of creating virtual characters, textures are usually used to create the costumes of virtual characters.

[0003] In related technologies, customized textures are created based on the model structure of the virtual character and the UV of the virtual character. However, during the live broadcast of a virtual character, if the virtual character needs to change costumes, using the method of customized textures to change costumes requires creating a set of textures for each set of virtual character costumes. Even if the difference between two sets of virtual character costumes is very small, two sets of textures are still needed. The number of textures is large, and the assets of the virtual character are numerous, which easily causes lags in the live broadcast. Summary of the Invention

[0061] To make the objectives, technical solutions, and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail with reference to the accompanying drawings.

[0062] Before introducing the technical solution of the embodiment of the present application, the nouns that may be used are first explained.

[0063] UV: Usually used to describe geometric models in three-dimensional space with two-dimensional texture coordinates. U represents the horizontal direction, and V represents the vertical direction. UV is to accurately correspond each point on the image to the surface of the model object, and the software performs image smoothing interpolation processing at the gap positions between points.

[0064] PBR (Physicallly-Based Rendering, physically based rendering): PBR is a method of shading and rendering that can more accurately express how light interacts with the surface. It is a process based on physically based rendering (PBR) or physically based shading (Physically-Based Shading, PBS). PBS usually refers to the shading concept. While PBR refers to rendering and lighting. Advantages: (1) The algorithm of PBR is based on physically approximate formulas, so the feedback of parameter adjustment conforms to natural habits. (2) From the artistic effect, the objects in the PBR process look very realistic under any lighting conditions. (3) A consistent workflow can be formed, and even different artists can continue to work well on the same object.

[0065] Please refer to Figure 1 , which shows a schematic diagram of the solution implementation environment provided by an embodiment of the present application. The solution implementation environment can be implemented as a system architecture for live streaming of virtual characters. The solution implementation environment may include: a terminal device 100 and a server 200.

[0066] The terminal device 100 includes, but is not limited to, electronic devices such as mobile phones, computers, smart home appliances, in-vehicle terminals, PCs (Personal Computers, personal computers), tablet computers, wearable devices, VR (Virtual Reality, virtual reality) devices, AR (Augmented Reality, augmented reality) devices, and MR (Mixed Reality, mixed reality) devices. A client of a target application can be installed and run in the terminal device 100, and the target application can provide a control function for virtual characters for users. Exemplarily, the target application can be the Unreal Engine or other applications with the control function of virtual characters, etc., and the present application does not make any limitations in this regard. Exemplarily, the target application can be used to create and modify the models of virtual characters, and can control the costumes of virtual characters, and can also control the display effects of the costumes of virtual characters. In addition, the form of the target application in the present application is not limited, including but not limited to Apps (Applications, applications) installed in the terminal device 100, applets, etc., and can also be in the form of a web page.

[0067] The server 200 can be an independent physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The server 200 can be the background server of the above target application, and is used to provide background services for the client of the target application.

[0068] The terminal device 100 and the server 200 can communicate with each other through a network, such as a wired or wireless network.

[0069] The technical solution provided by the embodiments of the present application can be applied not only to the live broadcast scenario of virtual characters, but also to scenarios such as game scenarios, VR, AR, XR (Extended Reality), etc. that require the display of virtual characters.

[0070] In the entire industrial chain of virtual digital humans, the generation of upstream virtual digital humans is mainly divided into three major links: modeling, driving, and rendering. Currently, there are mainly three methods for generating virtual digital human models. According to the level of human participation, they are, in order, manual modeling, modeling with the help of acquisition devices, and modeling with artificial intelligence. The upstream investment in virtual digital humans focuses on professional talents and related software and hardware costs. The pure manual modeling method has high costs and low production capacity.

[0071] People have tried to introduce virtual characters into the real business world. At this time, the production of virtual digital humans was mainly done by hand drawing. By the early 21st century, with the progress of computer technologies such as CG (Computer Graphics) and motion capture, modelers used relevant tool software to produce virtual humans, and most of the costs were still labor costs.

[0072] The specific steps of pure manual modeling are as follows: Use computer software to draw a design draft and depict the three views of the character; determine the three-dimensional graphics of the character according to the design drawings, and use 3D modeling software such as MAYA, 3DMax, and Zbrush to establish a basic three-dimensional model.

[0073] Other links in virtual human production also involve texture artists, riggers, animators, prop artists, 3D scene designers, etc. The manual production cycle is long and the cost is very high. The cost of this modeling method is mainly related to labor. One is determined by the size of the production team configuration, and the other is determined by the accuracy requirements of the modeling. The more realistic and detailed the virtual human is, the higher the modeling time and cost required.

[0074] The early stages of 3D content production mainly include art setting, character setting, etc. Today, we will mainly focus on the technical processes after these steps to discuss the technical processes of 3D content production, which mainly include modeling, texture mapping, rigging, animation production, visual effect production, lighting setup, rendering, post-processing, etc.

[0075] In addition to videos, the virtual world also requires interactive content production, that is, gamified content. And the game engine also involves production links such as model movement, lighting, and rendering.

[0076] Please refer to Figure 2 , which shows a schematic diagram of the 3D production pipeline provided by an embodiment of the present application. Next, the terms to be mentioned in the embodiments of the present application will be defined, and it can be understood in combination with Figure 2 to understand.

[0077] 1. Modeling: Generally, modelers need original paintings or photos as references to create 3D models that try to reproduce the reference images as much as possible. In order to determine the deformation units during movement and the mapping relationship with the texture, it is also necessary to determine the topology of the model, that is, the so-called "topology". Simply put, topology is to divide the model surface into grid-like areas, so 3D software also calls the model a "mesh object".

[0078] 2. Texturing: Texturing is also translated as "material" in some places. Applying textures can be simply understood as the process of coloring a 3D model. For the already topologized model, it is necessary to determine which area of the texture image each mesh corresponds to. This correspondence process from 3D to 2D is called "UV unwrapping", and the drawn texture map will be mapped back to the model, thus completing the coloring. However, in the actual CG industry, shading, as an important process in the rendering pipeline, is often not as simple as mapping the RGB values of a texture map to the model. Instead, it also requires the cooperation of multiple maps such as normal, specular, and roughness to construct a material ball, and then combined with lighting calculations to determine the final display effect of the model. Textures are drawn using 3D drawing software according to the existing UVs of the model. When the UVs or the model are modified, the texture map also needs to be modified correspondingly or redrawn according to the new UVs or model.

[0079] 3. Rigging: As the name implies, rigging means setting up a set of bones in the model. The displacement and rotation of each bone drive the mesh vertices on the nearby surface to move synchronously, and the mesh vertices at the joints are affected by multiple nearby bones simultaneously. Therefore, the core work of rigging is to determine the weight relationship of each vertex affected by each bone, and this process is also called skinning. Blend Shape is also called Morph Target in some DCC software and is the main means to solve non-rigid deformation. In practical applications, the rigging solution is determined by the specific project requirements. For example, in some mobile games with high requirements for client volume and running efficiency, a pure bone rigging solution is adopted, and even facial expressions are driven by virtual bones to move the mesh.

[0080] 4. Animating: Animating is to make the 3D model move, which is divided into two categories: active animation and passive animation. Active animation is relatively easy to understand - based on the bound controller, the animator can operate the bones for displacement and rotation, and transform the facial expressions. The production of active animation itself is often referred to as "keyframing animation". Passive animation refers to the movement that is not directly driven by subjective consciousness, mainly including cloth movement simulation, hair movement simulation, etc. Although we can bind virtual bones to clothes and hair and force the animator to produce these animations, because these movements have strong physical laws, the use of program simulation can usually achieve a level of realism and production efficiency that is beyond human reach. Therefore, these are usually calculated by the computer in the industry.

[0081] 5. Visual Effects: Visual Effects is generally abbreviated as VFX. Due to the overlap and differences between VFX, CGI, and special effects, there is no unified and standardized definition in the industry. Usually, the VFX in content production mostly includes particles, flames, smoke, sword glows, etc. In essence, it is still achieved through model and material changes, light processing, etc.

[0082] 6. Lighting: The lighting in the virtual environment is achieved by establishing mathematical models and algorithms to simulate the physical world lighting. The implementation of lighting settings is achieved by creating light sources such as directional lights, point lights, and area lights, and adjusting their properties such as intensity, color, and direction. Lighting is an important and indispensable part of the scene. Basic lighting applications can shape the light and dark relationship of the subject and create a three-dimensional sense of the picture, while advanced lighting applications can achieve specific artistic expressions.

[0083] 7. Rendering: To simply understand rendering, it can be considered as drawing the picture. The final presentation of the model, texture, visual effects, and lighting on the screen is achieved through rendering.

[0084] 8. Post-Processing: For video content production, after rendering 3D materials into a video, there are often post-processing processes such as editing, mixing, and 2D visual effects. This link is the same as the technology of traditional 2D video production and processing.

[0085] Most of the models and textures produced by the above process belong to customized assets. When adjusting the model structure or UV, the texture needs to be remade. The produced shader will also be affected accordingly. After the model is made, when the concept setting is adjusted greatly, the workload of model modification will increase accordingly, and the UV and texture will also need to be further modified accordingly. Customized models and textures are as Figure 3 shown, where 310 is the model of the virtual character, 320 is the UV, and 330 is the model of the virtual character after texturing.

[0086] Process of drawing textures: Get the model with UV, and use 3D drawing software to make textures according to the distribution of UV, so the UV cannot change. These all belong to customized models and textures, as Figure 3 shown. So in the Unreal Engine, these customized models and textures cannot adjust the texture details and color changes.

[0087] The embodiment of the present application provides a method for displaying the clothing of a virtual character. When there is a need to change the clothing of the virtual character, one-key clothing change can be realized, without re-texturing, which can effectively reduce the number and workload of textures, and can also alleviate the problem of live broadcast lag.

[0088] Please refer to Figure 4 , which shows a flowchart of a method for displaying the clothing of a virtual character provided by an embodiment of the present application. This method is executed by a first computer device. This method includes at least one of the following steps 410 to 430.

[0089] Step 410, when the clothing of the virtual character meets the condition of switching from the second display effect to the first display effect, determine the first index data from multiple groups of index data, where each group of index data includes at least one material and at least one attribute value corresponding to each material respectively. One material is used to describe an attribute of a component of the clothing of the virtual character, and different index data correspond to different display effects of the clothing of the virtual character, and the first index data corresponds to the first display effect.

[0090] In some embodiments, this method is executed by a terminal device. In some embodiments, this method is executed by the client of a target application installed in the terminal device. In some embodiments, the target application is the Unreal Engine.

[0091] In some embodiments, the method can be applied to the live broadcast process of virtual characters to achieve one - key switching of the display effect of virtual character costumes. In some embodiments, if the method is applied to the live broadcast process of virtual characters, the first computer device can be any computer device in the virtual live broadcast scene, and this computer device is used to control the virtual characters. The virtual scene may also include a rendering machine, lighting equipment, camera equipment, projection equipment, etc. Among them, the rendering machine is used to render virtual characters, virtual scenes, etc., the projection equipment is used to display virtual characters, virtual scenes, etc., the camera equipment is used to shoot virtual characters, virtual scenes, etc. to obtain a live video, and the lighting equipment is used to control the lighting during the live broadcast.

[0092] In some embodiments, the present application does not limit the conditions for the costume of the virtual character to switch from the second display effect to the first display effect.

[0093] In some embodiments, the conditions for the costume of the virtual character to switch from the second display effect to the first display effect include at least one of the following:

[0094] Receiving a signal for a switching operation of the display effect of the costume of the virtual character;

[0095] Reaching a preset time threshold;

[0096] Meeting a preset trigger condition.

[0097] In some embodiments, the condition for the costume of the virtual character to switch from the second display effect to the first display effect is receiving a signal for a switching operation of the display effect of the costume of the virtual character.

[0098] In some embodiments, the switching of the display effect of the costume of the virtual character can be controlled by an operator. If the operator clicks the switching control for the display effect of the costume of the virtual character, the target application program receives a signal for a switching operation of the display effect of the costume of the virtual character and starts executing from step 410 above.

[0099] In some embodiments, the condition for the costume of the virtual character to switch from the second display effect to the first display effect is reaching a preset time threshold.

[0100] In some embodiments, the preset time threshold can be determined according to the actual display scene of the virtual character. Exemplarily, the preset time threshold is determined according to the live broadcast duration of the virtual character, or according to the scene change time of the virtual character during the live broadcast.

[0101] In some embodiments, the preset time thresholds for different display effects may be the same or different. Exemplarily, the preset time threshold for the first display effect is threshold 1, and the preset time threshold for the second display effect is threshold 2. Threshold 1 and threshold 2 may be the same or different.

[0102] In some embodiments, the condition for the virtual character's clothing to switch from the second display effect to the first display effect is to meet a preset trigger condition. Exemplarily, during the live broadcast of the virtual character, the preset trigger condition is that the virtual scene where the virtual character is located changes. Then, when the virtual scene where the virtual character is located changes, the virtual character's clothing switches from the second display effect to the first display effect. In some embodiments, different display effects of the virtual character's clothing correspond to different virtual scenes where the virtual character is located. Exemplarily, the first display effect corresponds to the first virtual scene, and the second display effect corresponds to the second virtual scene. The first virtual scene and the second virtual scene are different.

[0103] In some embodiments, the virtual character's clothing includes clothing, accessories, shoes, socks, etc. for dressing up the virtual character.

[0104] In some embodiments, multiple sets of index data are stored in the terminal device. In some embodiments, multiple sets of index data are stored in the client of the target application installed in the terminal device.

[0105] In some embodiments, each set of index data includes at least one material and the attribute values respectively corresponding to at least one material. One material is used to describe an attribute of a component of the virtual character's clothing. Different index data correspond to different display effects of the virtual character's clothing. The first index data corresponds to the first display effect.

[0106] In some embodiments, the virtual character's clothing can be divided into multiple components. Exemplarily, the virtual character's accessories, shoes, socks, skirt, sleeves, and top can be respectively divided into one component.

[0107] In some embodiments, a component of the virtual character's clothing includes one or more attributes. One attribute is used to describe a characteristic of the component. Exemplarily, a component includes three attributes: color, brightness, and hue shift.

[0108] In some embodiments, different index data correspond to different display effects of the virtual character's clothing. Exemplarily, such as Figure 5The virtual character 510 shown has the main color of the clothing corresponding to the virtual character 510 being red for the first index data and green for the second index data. The main color of the clothing of the virtual character refers to the color that occupies the largest area on the clothing of the virtual character. Of course, the display effect of the clothing of the virtual character is not only distinguished by color. Here, it is only an exemplary illustration by color, and it can also be differences in the texture, pattern style, etc. of the clothing. This application does not make limitations in this regard.

[0109] Step 420: Based on the attribute values respectively corresponding to each material included in the first index data, adjust the attribute values of each component of the clothing of the virtual character.

[0110] In some embodiments, adjust the attribute values of the attributes of each component of the clothing of the virtual character to the attribute values of the corresponding materials in the first index data.

[0111] In the related art, if you want to adjust the clothing of a virtual character, you need to remap. Even when switching the color of the clothing of the virtual character, you need to remap because the related art does not provide a method for adjusting the attribute values of each component of the clothing of the virtual character. In this regard, the embodiments of this application provide a method that can control the attributes of each component of the clothing of the virtual character.

[0112] In some embodiments, the attributes of each component of the clothing of the virtual character are controlled by a structure. In some embodiments, the structure may also have other names. This application does not make limitations in this regard. Exemplarily, the structure may also be referred to as a controller.

[0113] In some embodiments, the structure includes at least one material, and at least one material is set as a material dynamic instance. At least one material in the structure is respectively associated with the attributes of each component of the clothing of the virtual character. A material dynamic instance means that the attribute value corresponding to each material is dynamically adjusted.

[0114] In some embodiments, at least one material in the structure is respectively associated with the attributes of each component of the clothing of the virtual character, which means that by adjusting the attribute value of the material in the structure, the attribute value of the corresponding component of the material on the clothing of the virtual character can be correspondingly controlled.

[0115] In some embodiments, a material dynamic instance means that the attribute value of the material can be selected and set from the preset attribute values.

[0116] In some embodiments, the above step 420 can be implemented as the following step 421.

[0117] Step 421: Invoke the structure. Based on the attribute values corresponding to each material included in the first index data through the structure, adjust the attribute values of each component of the virtual character's clothing, where the structure is used to control the attributes of each component of the virtual character's clothing.

[0118] In some embodiments, invoke the structure. Through the structure, adjust the j-th attribute value of the i-th component of the virtual character's clothing to the attribute value corresponding to the m-th material in the first index data, where the m-th material is used to describe the j-th attribute of the i-th component, and i, j, and m are positive integers.

[0119] In some embodiments, adjust the attribute value corresponding to the m-th material in the structure to the attribute value corresponding to the m-th material in the first index data, and then the j-th attribute value of the i-th component of the virtual character's clothing can be adjusted to the attribute value corresponding to the m-th material in the first index data.

[0120] In some embodiments, the structure can be reused. There is no need to recreate a structure every time the display effect of the virtual character is switched. Only the attribute values of each material in the structure need to be adjusted. Exemplarily, if it is necessary to switch the display of the virtual character's clothing from the first display effect to the third display effect, the attribute values corresponding to each material in the structure can be adjusted according to the attribute values corresponding to each material in the third index data.

[0121] Step 430: Render the virtual character's clothing according to the attribute values of each component of the virtual character's clothing, so that the virtual character's clothing presents the first display effect.

[0122] In some embodiments, send the attribute values of each component of the virtual character's clothing to the renderer, and the renderer renders the virtual character's clothing, so that the virtual character's clothing presents the first display effect.

[0123] The technical solution provided by the embodiments of the present application, when it is necessary to switch the display effect of the virtual character's clothing, only need to select a set of index data from multiple sets of index data, and adjust the attribute values of each component of the virtual character's clothing based on this set of index data, so as to achieve the purpose of adjusting the display effect of the virtual character's clothing. There is no need to remake the texture map corresponding to the virtual character's clothing, reduce the number of texture maps, reduce the workload of the staff, and at the same time, it can effectively avoid the problem that the virtual character is prone to jitter during the live broadcast due to too many assets.

[0124] Please refer to Figure 6 , which shows a flowchart of a method for displaying the clothing of a virtual character provided by another embodiment of the present application. This method is executed by a second computer device. This method may include at least one of the following steps 610-630.

[0125] Step 610: Determine at least one material of the virtual character's clothing, where one material is used to describe an attribute of a component of the virtual character's clothing.

[0126] In some embodiments, the first computer device and the second computer device may be the same computer device or different computer devices, and this application does not limit this.

[0127] In some embodiments, at least one material may be determined according to the attributes of the respective components of the virtual character's clothing.

[0128] In some embodiments, divide the virtual character's clothing into at least one component, and determine the respective corresponding attributes of each component. Determine the respective corresponding attributes of each component of the virtual character's clothing as at least one material.

[0129] In some embodiments, determine at least one material; divide the virtual character's clothing into at least one component, and determine the respective corresponding attributes of each component; determine the correspondence between at least one material and the respective corresponding attributes of each component of the virtual character's clothing.

[0130] Step 620: Based on at least one material, create a blueprint corresponding to the virtual character, where the blueprint includes multiple sets of index data, and each set of index data includes at least one material and the respective corresponding attribute values of at least one material, and different index data corresponds to different display effects of the virtual character's clothing.

[0131] In some embodiments, create multiple sets of index data and store the multiple sets of index data in the blueprint.

[0132] In some embodiments, the blueprint further includes a structure. In some embodiments, the blueprint is used to associate multiple sets of index data with the structure. In some embodiments, the blueprint can associate multiple sets of index data with the structure to achieve the purpose of one-key switching of the attribute values corresponding to each material in the structure. Exemplarily, after the blueprint associates the structure with the index data, if the first index data is selected, the attribute values of each material in the structure can be adjusted to the attribute values corresponding to each material in the first index data with one key, without having to adjust the attribute values of each material in the structure one by one.

[0133] In some embodiments, the above step 620 can be implemented as at least one of the following steps 621 to 624.

[0134] Step 621: Based on at least one material, create a structure, where the structure is used to control the attributes of the respective components of the virtual character's clothing.

[0135] In some embodiments, based on at least one material, a structure is created, and each material in the structure is associated with the attributes of the components of the clothing of the virtual character corresponding to the material, so that adjusting the attribute values of the materials in the structure can achieve the purpose of adjusting the attribute values of the corresponding components on the clothing of the virtual character.

[0136] Step 622, set at least one material in the structure as a material dynamic instance, where a material dynamic instance means that the attribute value corresponding to each material is dynamically adjusted.

[0137] In some embodiments, since the structure can be reused, there is no need to recreate a structure every time the display effect of the virtual character is switched. It is only necessary to adjust the attribute values of each material in the structure. Therefore, the attribute values of each material in the structure should be adjustable, or in other words, dynamically adjustable and variable.

[0138] In some embodiments, a material dynamic instance means that the attribute value of the material can be selected and set from the preset attribute values.

[0139] In some embodiments, for each of at least one material, determine at least one preset attribute value corresponding to the material, where the attribute value corresponding to the material is determined from at least one preset attribute value corresponding to the material.

[0140] In some embodiments, the preset attribute value corresponding to the material can be determined according to the attributes of the components of the clothing of the virtual character corresponding to the material. Exemplarily, if the material corresponds to the color of a certain component of the clothing of the virtual character, the preset attribute value of the material can be a color atlas, and the corresponding color can be selected from the color atlas. Exemplarily, if the material corresponds to the brightness of a certain component of the clothing of the virtual character, the preset attribute value of the material can be a numerical range, and the corresponding brightness value can be selected from the numerical range.

[0141] Step 623, based on the structure, create multiple groups of index data, and there is at least one material corresponding to different attribute values in any two groups of index data.

[0142] In some embodiments, by respectively determining the attribute values corresponding to each material in the structure, the attribute values respectively corresponding to each material in the structure can be stored as a group of index data.

[0143] In some embodiments, for each group of index data, obtain the attribute values respectively corresponding to at least one material in the structure; store the attribute values respectively corresponding to at least one material as a group of index data.

[0144] In some embodiments, different groups of index data may be set separately, or may be modified based on a group of index data, which is not limited in the present application.

[0145] Step 624, linking the structure and multiple groups of index data to obtain a blueprint.

[0146] In some embodiments, linking a structure and multiple groups of index data means associating multiple groups of index data with the structure to achieve the purpose of switching the property values ​​corresponding to each material in the structure with one click. Exemplarily, after the blueprint associates the structure with the index data, if the first index data is selected, the property values ​​of each material in the structure can be adjusted to the property values ​​corresponding to each material in the first index data with one click, without having to adjust the property values ​​of each material in the structure one by one.

[0147] In some embodiments, the above step 620 also includes the following step 625.

[0148] Step 625: Create a skeletal mesh, which is used to associate the clothing of the virtual character with the model of the virtual character.

[0149] In some embodiments, the skeleton mesh is used to associate the costume of the virtual character with the model of the virtual character, so that the costume of the virtual character can move with the movement of the model of the virtual character. For example, when the virtual character raises his hand, the costume of the virtual character can also move accordingly to present a reasonable effect.

[0150] In some embodiments, the above step 624 may be implemented as the following step 624a.

[0151] Step 624a, linking the structure, the skeletal mesh and multiple groups of index data to obtain a blueprint.

[0152] In some embodiments, the skeleton mesh is associated with the structure and multiple groups of index data, so that even if the virtual character changes its action, the display effect of the virtual character's clothing can be guaranteed not to be exposed.

[0153] Step 630: Based on the first index data in the plurality of groups of index data, control the clothing of the virtual character to be displayed with a first display effect, wherein the first index data corresponds to the first display effect.

[0154] In some embodiments, after a set of index data is set, a display effect corresponding to the set of index data may be previewed.

[0155] In some embodiments, based on the first index data in the plurality of sets of index data, the target application controls the clothing of the virtual character to be displayed with the first display effect. Exemplarily, the target application is Unreal Engine.

[0156] The technical solution provided by the embodiments of the present application creates a blueprint corresponding to a virtual character through multiple materials of the virtual character's clothing. The blueprint includes multiple sets of index data, and different index data corresponds to different display effects, enabling the display effects of the virtual character's clothing to be switched with one key. When switching the display effect of the virtual character's clothing, there is no need to remake the texture map, reducing the number of texture maps.

[0157] The present application also gives an exemplary embodiment on how to texture the virtual character's clothing.

[0158] Please refer to Figure 7 , which shows a flowchart of a texture mapping method provided by an embodiment of the present application. This method is executed by a second computer device. This method may include at least one of the following steps 710 to 740.

[0159] Step 710, create a model of the virtual character.

[0160] In some embodiments, the virtual character can be any kind of virtual character. Exemplarily, the virtual character can be a virtual character in human form, or a virtual character in animal form. Exemplarily, the virtual character can be a virtual character in cartoon form, or a virtual character in simulation form.

[0161] Step 720, obtain at least one UV texture map corresponding to the virtual character's clothing.

[0162] In some embodiments, the number of UV texture maps corresponding to the virtual character's clothing can be determined based on the material of the virtual character's clothing. Exemplarily, if there are two materials of silk and embroidery for the virtual character's clothing, the virtual character's clothing can be divided into two UV texture maps, where one UV texture map corresponds to the silk fabric part and the other corresponds to the embroidery fabric part.

[0163] In some embodiments, the number of UV texture maps corresponding to the virtual character's clothing can be determined based on the style of the virtual character's clothing. Exemplarily, if the virtual character's clothing has two parts, a skirt and a shawl, the skirt and the shawl can be divided into two UV texture maps, where one UV texture map corresponds to the skirt part and the other corresponds to the shawl part.

[0164] Step 730, create a master material based on at least one UV texture map, and the master material is used to construct the model of the virtual character's clothing on the model of the virtual character.

[0165] In some embodiments, the master material is a seamless tileable texture map that can fit the model of the virtual character so that the virtual character's clothing can fit the model of the virtual character.

[0166] Step 740, create a material function, which is used to control the attributes of at least one UV map.

[0167] In some embodiments, the material function is used to control the attributes of at least one UV map so that the UV map can obtain the desired visual effect.

[0168] In some embodiments, the material function includes at least one of the following: a texture material function corresponding to each of the at least one UV map, a normal material function corresponding to each of the at least one UV map, a texture quality material function corresponding to each of the at least one UV map, and an occlusion relationship function.

[0169] In some embodiments, the texture material function corresponding to the UV map is used to control the texture of the UV map.

[0170] In some embodiments, the normal material function corresponding to the UV map is used to control the contrast of the UV map. In some embodiments, the normal material function is used to simulate the physical structure of the UV map so that the UV map can present a visual structural effect. For example, by adjusting the normal material function of the UV map, the UV map can present a three-dimensional visual effect.

[0171] In some embodiments, the texture quality material function corresponding to the UV map is used to control the texture quality of the UV map. In some embodiments, the texture quality material function is used to simulate the brightness of the UV map so that the UV map can present a visual texture quality effect. For example, by adjusting the texture quality material function of the UV map, the UV map can present a more textured effect. In some embodiments, the texture quality material function can also be referred to as a roughness material function.

[0172] In some embodiments, the occlusion relationship function is used to control the occlusion relationship of at least one UV map during display.

[0173] In some embodiments, for each UV map, the normal map of the UV map is displayed using a first channel, and the normal map is used to characterize the contrast of the UV map; the roughness map of the UV map is displayed using a second channel, and the roughness map is used to characterize the texture quality of the UV map; the occlusion map of the UV map is displayed using a third channel, and the occlusion map is used to characterize the occlusion relationship of the UV map during display; wherein, the first channel, the second channel, and the third channel are simultaneously displayed as the clothing of a virtual character obtained by mapping the UV map.

[0174] In some embodiments, the first channel can be any one or more of the R, G, and B channels.

[0175] In some embodiments, the second channel can be any one or more of the R, G, and B channels.

[0176] In some embodiments, the third channel is the A channel.

[0177] Exemplarily, the first channel is the RG channel, the second channel is the B channel, and the third channel is the A channel.

[0178] Next, an example will be given where the clothing of a virtual character includes two UV maps, where UV1 corresponds to the silk fabric part and UV2 corresponds to the embroidered fabric part, to provide an exemplary description of the UV maps.

[0179] As Figure 8 shown is the effect diagram of the multi-channel map corresponding to UV1. Figure 9 is the normal map corresponding to UV1. Figure 10 is the texture map corresponding to UV1. Figure 9 The normal map shown, and Figure 10 the texture map shown are displayed simultaneously, which is the Figure 8 display effect shown.

[0180] As Figure 11 shown is the effect diagram of the multi-channel map corresponding to UV2. Figure 12 is the normal map corresponding to UV2. Figure 13 is the texture map corresponding to UV2. Figure 14 is the occlusion map corresponding to UV2. Figure 12 The normal map shown, and Figure 13 the texture map shown are displayed simultaneously, which is the Figure 11 display effect shown.

[0181] Among them, since there is an occlusion relationship between the embroidered fabric corresponding to UV2 and the silk fabric corresponding to UV1 (the embroidery covers the silk), UV2 has an occlusion map, and the occlusion map can control the occlusion range of UV2 on UV1. The clothing of the rendered virtual character is as Figure 15 shown, and the embroidered fabric part 1510 covers the silk fabric 1520.

[0182] The technical solution provided by the embodiments of the present application performs UV mapping through a four-way continuous master material, so that it is not necessary to adjust the UV map according to the model of the virtual character during the mapping process. The master material can fit the model of the virtual character, reducing the workload of staff in processing the map.

[0183] Please refer to Figure 16 , which shows a flowchart of a method for displaying the clothing of a virtual character provided by another embodiment of the present application. Next, the method provided by the embodiments of the present application will be introduced by way of example in combination with Figure 16 .

[0184] First, a virtual character model needs to be created. To facilitate the introduction of the texture mapping method in the embodiments of this application, it is assumed here that we have created a virtual character model with multiple sets of UVs.

[0185] Among them, UV1 is used to present the texture and texture of the base fabric, and UV2 is used to present the texture and texture of the embroidered part. Multichannel texture mapping is performed on UV1 and UV2 respectively. The method of multichannel texture mapping can refer to the introduction of Figure 8 from 15 in the above embodiments, and this application will not elaborate here.

[0186] Create a master material based on UV1 and UV2.

[0187] Create a material function. The material function can include a texture material function, a normal material function, a texture material function, an occlusion relationship function, etc.

[0188] Create a blueprint. In some embodiments, the blueprint includes a structure, multiple sets of index data, and a skeletal mesh. Exemplarily, as Figure 17 shown, the blueprint includes a skeletal mesh.

[0189] As Figure 18 shown, the structure includes at least one material and the corresponding property values of at least one material. The name of each material can be set by the staff based on their own experience or automatically generated, and this application does not limit this. In some embodiments, as Figure 19 shown, at least one material in the structure is set as a material dynamic instance. In some embodiments, the material properties of the property values corresponding to different materials are different. Exemplarily, the color property is a linear color, the parameter is a floating point number, and the texture mapping property is a texture 2D.

[0190] In some embodiments, multiple sets of index data are set based on the structure. Exemplarily, as Figure 20 shown, the properties of at least one material are set by referring to the structure. The variable type in the figure refers to the properties listed in the structure.

[0191] The linkage between the dynamic material instance, the skeletal mesh, and the structure is as Figure 21 shown. After the blueprint is set up, the material color, texture, and texture can be adjusted based on the index data.

[0192] After the above settings are completed, one-key switching of the virtual character's clothing can be achieved. Exemplarily, as Figure 22 shown, only the index of the selected index data needs to be adjusted in the control 2210 to achieve the switching of the display effect of the virtual character's clothing. For example, if the index in the control 2210 is adjusted from 1 to 2, the display effect of the virtual character's clothing can be switched from display effect 1 to display effect 2.

[0193] The technical solution provided by the embodiments of the present application creates a blueprint corresponding to a virtual character through multiple materials of the virtual character's clothing. The blueprint includes multiple groups of index data, and different index data correspond to different display effects, enabling the clothing of the virtual character to achieve one-key switching of display effects. When switching the display effect of the virtual character's clothing, there is no need to remake the texture map, reducing the number of texture maps. In addition, it can also enable real-time clothing change in the Unreal Engine. This master material can be reused for other assets and will not be discarded due to changes in UV and models. By ensuring the effect on the material in the Unreal Engine, the number of texture maps can be significantly reduced, ensuring the performance and frame rate of virtual live broadcasts and reducing the production cost of 3D assets.

[0194] To implement the above functions, it is also necessary to digitize some display effects of the UV texture map so that the display effect of the UV texture map can be adjusted based on the Unreal Engine. What is the digitization process? The image is converted into digital information and can be edited in real time using numbers in the Unreal Engine.

[0195] Exemplarily, as Figure 23 shown is the normal map material function. As Figure 24 shown, connect the normal map material function 2410 to the master material 2420 so that the parameter attribute of the normal strength of the master material can be controlled based on the normal map material function.

[0196] Exemplarily, as Figure 25 shown is the texture map material function. The repeatability, offset, rotation, etc. of the texture can all be adjusted through the texture map material function to avoid additional texture map requirements due to minor changes.

[0197] Exemplarily, one set of UV is used for the base texture and fabric texture, and the other set is used for the embroidery effect; then how to handle the occlusion relationship between these two sets of texture maps? How can the texture map of UV2 only display the embroidery part and filter out other areas so that UV2 can be combined with the base fabric of UV1 for display? In this case, it is necessary to create an occlusion relationship function for the two sets of UV, and automatically filter out the areas outside the embroidery through the Mask of the embroidery texture map. As Figure 26 shown, controlling the parameter of the A channel can achieve automatically filtering out the areas outside the embroidery through the Mask of the embroidery texture map.

[0198] As Figures 27 to 30 shown is a schematic diagram of the digitization of the gradient effect. If a gradient effect needs to be created during the texture map production process, first draw a gradient layer and then overlay it on the color layer. Here, the gradient effect is obtained through the calculation form of coordinates and the offset value and contrast can be adjusted through numerical values. Among them, Figures 27 - 30 shown are schematic diagrams of four gradient effects with different gradient directions and / or positions of the gradient axes. Among them,Figure 27 and Figure 28 shown is a pair with the same gradient axis position but different gradient directions; Figure 29 and Figure 30 shown is a pair with the same gradient axis position but different gradient directions. As Figure 31 shown, for the gradient effect of the skirt, the gradient range, intensity, direction, offset value, and axis can all be adjusted in real time through numerical values. Of course, not only the gradient effect, but other display effects can also be represented digitally. Here, only the gradient effect is used as an example for illustrative purposes. For example, the shadow effect can also be represented digitally.

[0199] As Figure 32 shown, a schematic diagram of the material properties that need to be digitally processed during the costume change of a virtual character's clothing is also given. Of course, for different virtual characters, or for the clothing of different virtual characters, the material properties that need to be digitally processed during the costume change will be different. Here, it is only for illustrative purposes.

[0200] The following is an embodiment of the device of the present application, which can be used to execute the method embodiment of the present application. For the details not disclosed in the device embodiment of the present application, please refer to the method embodiment of the present application.

[0201] Please refer to Figure 33 , which shows a block diagram of a virtual character's clothing display device provided by an embodiment of the present application.

[0207] In some embodiments, an adjustment module 3320 is configured to call the structure, and through the structure, adjust the j-th attribute value of the i-th component of the clothing of the virtual character to the attribute value corresponding to the m-th material in the first index data, where the m-th material is used to describe the j-th attribute of the i-th component, and i, j, and m are positive integers.

[0228] Please refer to Figure 35, which shows a block diagram of a computer device 3500 provided by an embodiment of the present application. The computer device 3500 can be any electronic device with data calculation, processing, and storage functions. The computer device 3500 can be used to implement the virtual character clothing display method provided in the above embodiments.
