[0060] First, the following terms are explained:

[0061] Unreal Engine: A comprehensive game engine developed by Epic Games for creating interactive 3D and 2D content. Unreal Engine can be applied to game development, virtual reality (VR), augmented reality (AR), film production, architectural visualization and other fields.

[0062] Tint: A specific portion or area on a 3D model or object that can be used to control certain appearance or behavior characteristics of the object or character.

[0063] Material: A virtual material used to control and render the appearance of a target model. Through materials, you can define the visual and physical properties of an object, such as color, texture, gloss, reflection, transparency, etc.

[0064] Secondly, in order to facilitate those skilled in the art to understand the technical solutions provided in the embodiments of the present application, the relevant technologies are described below:

[0065] Unreal Engine can be used to achieve real-time interactive experience, such as in game development, virtual reality (VR) and other fields. Unreal Engine can be used to set the appearance attributes and effects associated with 3D models, such as changing the color of a 3D model so that the 3D model switches from one color to another. However, the current 3D model color switching effect is poor, which reduces the user experience.

[0066] To this end, an embodiment of the present application provides a technical solution for model dynamic color generation based on the Unreal engine. In this technical solution: (1) For the same 3D model, different dynamic color effect parameters can be set to achieve the dynamic effect of the model changing in different time periods and in multiple different colors.

(3) In the engine or when the game is running, the content of the functional module can be flexibly adjusted according to the actual needs to achieve a smooth 3D model color dynamic change effect. See below for details.

[0067] Embodiment 1

[0068] Figure 1 The flowchart of the method for dynamic color generation of a model based on the Unreal engine according to the first embodiment of the present application is schematically shown.

[0069] like Figure 1 As shown, the method for generating dynamic color of a model based on the Unreal engine may include steps S100 to S108, wherein:

[0070] Step S100, obtaining material information of the target model.

[0071] Step S102, obtaining the dyeing area information of each material on the target model according to the material information, wherein the same dyeing area corresponds to the same color on each material at the same time.

[0072] Step S104, obtaining dynamic color parameters for the dyeing area.

[0073] Step S106, obtaining a frame color value corresponding to each frame of the dyed area in the dynamic process according to the dynamic color parameter.

[0074] Step S108 , dynamically rendering the dyed area according to the frame color value corresponding to each frame to generate a target model with dynamically changing colors.

[0075] The method for generating dynamic colors of a model based on the Unreal engine provided in this embodiment obtains the dyeing area of ​​the target model and the dynamic color parameters of the dyeing area. According to the dynamic color parameters of the dyeing area, the frame color value corresponding to each frame of the dyeing area during the dynamic change process is determined. Then, according to the frame color value corresponding to each frame, the dyeing area is dynamically rendered frame by frame, so that the color of the target model continues to change dynamically with the number of frames, thereby improving the dynamic color switching effect of the target model and enhancing the user experience.

[0076] The following combination Figure 1 , each step in steps S100 to S108 and other optional steps are described in detail.

[0077] Step S100 , get the material information of the target model.

[0078] The target model may be a 3D model generated based on the Unreal engine, which refers to a virtual object or object in a three-dimensional space, and may be a character, scene, object, building, or other object in a game world. In an exemplary application, the target model may be a clothing object such as a top or a skirt, or may be other objects.

[0079] The material information may be setting information of material properties used to render and present the target model. The appearance of the target model may be determined based on the material information, such as visual characteristics such as color, texture, reflection, illumination, transparency, etc. Exemplarily, the material information may include color partition information on a map, color partition mark information on a material, etc.

[0080] Step S102 , according to the material information, the dyeing area information of each material on the target model is obtained, and the same dyeing area corresponds to the same color on each material at the same time.

[0081] A target model may include one or more dyed regions. In an exemplary application, Figure 2 As shown, the target model includes two dyeing areas, namely, dyeing area 1 "orange" and dyeing area 2 "blue".

[0082] Each dyeing area may include one or more color partitions, and the colors of the one or more color partitions are the same. It should be noted that by modifying the color of a dyeing area, the colors of the one or more color partitions corresponding to the dyeing area can be changed at the same time, and the colors of the one or more color partitions are the same.

[0083] Step S104 , obtain dynamic color parameters for the dyeing area.

[0084] Each dyeing area corresponds to a set of dynamic color parameters. When designing the target model, the corresponding dynamic color parameters can be modified in real time in the engine or in-game interface to adjust the specific color value and dynamic change duration of the dyeing area in real time, and preview the dynamic color change effect of the dyeing area.

[0085] In an optional embodiment, the target model includes one or more materials, each material includes one or more color partitions. Each color partition is provided with an identifier, and the color partitions belonging to the same dyeing area have the same identifier.

[0086] Correspondingly, the step 204 may also include:

[0087] According to the identifier of the color partition, a target color partition corresponding to the dyeing partition is obtained from the one or more materials.

[0088] The dynamic color parameter of the dyed area is used to instruct the target color partition to change dynamically.

[0089] The material is a virtual material used to control and render the appearance of the target model. Through the material, the visual attributes of the target model, such as color, lighting, texture, etc., can be defined. And the material can use a map to divide a plurality of different color partitions.

[0090] The identifier is used to identify which dye region each color partition on the material belongs to.

[0091] In the above optional embodiment, based on the identifier of the color partition, the target color partition corresponding to the dyeing area can be quickly obtained from one or more materials in the target model, thereby improving the efficiency of obtaining the target color partition corresponding to the dyeing area, and further improving the efficiency of dynamic color change of the target color partition.

[0092] In an optional embodiment, each material is associated with a dynamic sub-material, and the target color partition includes multiple sub-partitions. Figure 3 As shown, the step 104 further includes:

[0093] Step S300, determining a plurality of target dynamic sub-materials corresponding one-to-one to the plurality of sub-partitions.

[0094] Step S300, assigning corresponding dynamic color parameters to each target dynamic sub-material. The corresponding dynamic color parameters are a group of parameters in the dynamic color parameters of the dyeing area, and are used to instruct the corresponding sub-area to change dynamically.

[0095] The dynamic sub-material is a material instance that is dynamically created and modified at runtime. Dynamic sub-materials allow the properties of materials, such as color, texture, lighting, transparency, etc., to be modified in real time while the game or application is running, thereby achieving dynamic visual effects and interactivity of the target model.

[0096] The target color partition may include multiple sub-partitions, and the multiple sub-partitions have the same identifier and are marked as belonging to the same dyeing area. Figure 4 As shown, the dyeing area 1 includes the following sub-areas: sub-area A2, sub-area B1, and sub-area C2. It should be noted that by modifying the color of the dyeing area, the colors of multiple sub-areas corresponding to the dyeing area can be changed at the same time.

[0097] In an exemplary application, such as Figure 4 As shown, the target model may include three materials, namely material A, material B, and material C. Correspondingly, the target model may include three dynamic sub-materials, specifically: material A is associated with dynamic sub-material A, material B is associated with dynamic sub-material B, and material C is associated with dynamic sub-material C. In addition, the target model includes two dyeing areas, namely dyeing area 1 and dyeing area 2. Among them, dyeing area 1 includes the following sub-partitions: sub-partition A2, sub-partition B1, and sub-partition C2. Dyeing area 2 includes the following sub-partitions: sub-partition A1, sub-partition A3, sub-partition B2, sub-partition C1, and sub-partition C3. According to the association relationship between the material and the dynamic sub-material, the target dynamic sub-material corresponding to each sub-partition can be determined. Specifically: the target dynamic sub-material corresponding to sub-partition A2 is dynamic sub-material A; the target dynamic sub-material corresponding to sub-partition B1 is dynamic sub-material B; the target dynamic sub-material corresponding to partition C2 is dynamic sub-material C. Correspondingly, the correspondence between the sub-partitions in dyeing area 2 and the target dynamic sub-materials is as follows: the target dynamic sub-material corresponding to sub-partition A1 is dynamic sub-material A; the target dynamic sub-material corresponding to sub-partition A3 is dynamic sub-material A; the target dynamic sub-material corresponding to sub-partition B2 is dynamic sub-material B; the target dynamic sub-material corresponding to sub-partition C1 is dynamic sub-material C; the target dynamic sub-material corresponding to sub-partition C3 is dynamic sub-material C.

[0098] In the above optional embodiment, the target dynamic sub-material corresponding to the sub-partition is determined, and then the corresponding dynamic color parameters are assigned to the target dynamic sub-material, so that the color of the corresponding sub-partition can be dynamically changed according to the target dynamic sub-material to which the corresponding dynamic color parameters are assigned, thereby improving the color switching effect of the target model.

[0099] In an optional embodiment, the method further comprises:

[0100] When the target material corresponding to the sub-partition has no dynamic sub-material set, a target dynamic sub-material corresponding to the target material is created.

[0101] In an exemplary application, it is determined whether the target material corresponding to the sub-partition in the target model is the first time to set the dynamic sub-material. If the target material is not set with the corresponding dynamic color effect, that is, the dynamic sub-material is not set, a target dynamic sub-material corresponding to the target material is created and stored in the target material.

[0102] In the above optional embodiment, when the target material corresponding to the sub-partition has not set a dynamic sub-material, a target dynamic sub-material corresponding to the target material is created, so that the real-time dynamic change of the target model color can be realized according to the created target dynamic sub-material, thereby improving the color switching effect of the target model.

[0103] In an optional embodiment, the method may further include: caching the target dynamic sub-material in a preset data structure.

[0104] The data structure may exist in the form of an array or a structure, etc. It should be noted that the data structure may be arranged according to the color partitions in the corresponding material to improve the efficiency of subsequent search for the corresponding material according to the color. In the above optional embodiment, caching the target dynamic sub-material in a preset data structure can improve the efficiency of accessing the target dynamic sub-material when the target model performs dynamic color changes.

[0105] In an optional embodiment, the method may further include:

[0106] In the case where the target material corresponding to the sub-partition has been set with a historical dynamic sub-material, the historical dynamic sub-material is set as the target dynamic sub-material.

[0107] In an exemplary application, it is determined whether the target material corresponding to the sub-partition in the target model is set to a dynamic sub-material for the first time. If the target material has created a historical dynamic sub-material, that is, the target material has been set with a historical dynamic sub-material, the historical dynamic sub-material is set as the target dynamic sub-material.

[0108] In the above optional embodiment, the historical dynamic sub-material is set as the target dynamic sub-material, so that when the color of the sub-partition is modified subsequently, the dynamic sub-material can be directly used without having to create a corresponding dynamic sub-material each time the color of the sub-partition is modified, thereby reducing the occurrence of running jams caused by multiple creation of dynamic sub-materials.

[0109] Step S106 , according to the dynamic color parameter, obtain the frame color value corresponding to each frame of the dyeing area in the dynamic process.

[0110] The frame color value refers to the color attribute value of the dyed area in each frame (a single image frame in a game or animation) during the dynamic change process. The frame color value can be a color vector, and the frame color value can be represented in a variety of ways, such as RGB (red, green, blue), HSV (hue, saturation, brightness), CMYK (cyan, magenta, yellow, and key), etc. For example, when the frame color value is represented by RGB, it can be (R=255, G=0, B=0).

[0111] In an optional embodiment, the dynamic color parameter of the dyeing area includes a first correspondence between a color sequence of the dyeing area and a time period. Figure 5 As shown, step 106 includes:

[0112] Step 500, setting a preset display frame number.

[0113] Step 500: setting a second corresponding relationship between the preset display frame number and the time period.

[0114] Step 500: Obtain a frame color value corresponding to each frame of the dyed area according to the first corresponding relationship and the second corresponding relationship.

[0115] The dynamic color change parameters of the dyeing area may also include: the corresponding color sequence combination of the sub-time period in the time period of the dynamic color change. Exemplarily, the time period of the dynamic color change of the dyeing area is 0-8 seconds, and the color changes from red to yellow. Wherein, the time period may include multiple sub-time periods, and the multiple sub-time periods may correspond to different color changes, specifically: in the sub-time period of 0-2 seconds, the color of the dyeing area changes from red to orange; in the sub-time period of 2-5 seconds, the color of the dyeing area changes from orange to red; in the sub-time period of 5-6 seconds, the color of the dyeing area changes from red to orange, and in the sub-time period of 5-6 seconds, the color of the dyeing area changes from orange to yellow. It should be noted that the color and time corresponding to the sub-time period can be selected according to actual conditions, and are not limited here.

[0116] The color sequence can be used to describe the sequence of color changes of the dyeing area over time. The time period can be the time period of the color change of the dyeing area. It should be noted that the color sequence and time period in the dynamic color change parameter can be designed according to actual needs to achieve the effect of dynamic change of the target model in different time periods and different colors.

[0117] In an exemplary application, such as Figure 4As shown, assuming that the time period of dyeing area 1 is 2 seconds, the frame color value is expressed in RGB (red, green, blue), and the color sequence of the dyeing area is: dynamically changing from orange to blue, that is, the RGB color value of dyeing area 1 changes from orange (237, 125, 49) to blue (91, 155, 213). Correspondingly, the partial corresponding relationship in the first corresponding relationship can be: when dyeing area 1 is at 0 seconds, the RGB color value is orange (237, 125, 49), when dyeing area 1 is at 1 second, the RGB color value is (200, 130, 100), when dyeing area 1 is at 1.5 seconds, the RGB color value is (150, 140, 160), and when dyeing area 1 is at 2 seconds, the RGB color value is blue (91, 155, 213). It should be noted that the first time corresponding relationship can be set according to actual conditions and is not limited here.

[0118] The preset display frame rate is the display frame rate required in the engine or the game. For example, the preset display frame rate may be 30 frames per second or 60 frames per second.

[0119] In an exemplary application, the preset display frame number may be 30 frames per second, and the time period may be 2 seconds. According to the preset display frame number, the time period is associated with the preset display frame number to obtain a second corresponding relationship. A partial corresponding relationship in the second corresponding relationship may be: at 0 seconds, the dyed area is at the 0th frame; at 1 second, the dyed area is at the 30th frame; at 1.5 seconds, the dyed area is at the 45th frame; at 2 seconds, the dyed area is at the 60th frame.

[0120] In an exemplary application, the frame color value corresponding to each frame of the dyeing area in the time period of the color dynamic change process can be obtained according to the color transition algorithm. The color transition algorithm can be selected according to the actual situation such as the color representation method of the dyeing area, the corresponding relationship between the color sequence and the number of frames (such as linear or nonlinear). The color transition algorithm can be: (1) Linear interpolation (Lerp): Create transition colors by linear interpolation between two colors. For example, in the RGB color space, linear interpolation from red to green can be performed on each color channel separately. Linear interpolation between red (255, 0, 0) and green (0, 255, 0) will produce various yellow tones. (2) Bezier Curve: Create complex color transition effects by defining colors on control points. (3) HSL / HSV transition: A color transition algorithm based on the HSL (hue, saturation, brightness) or HSV (hue, saturation, brightness) color model. The HSL / HSV transition algorithm allows transition on the hue wheel, so that the target model achieves a more natural color transition effect. It should be noted that when obtaining the frame color value corresponding to each frame of the dyed area, different color transition algorithms can be selected according to actual conditions, so that the dyed area can achieve different color change effects within the time period and when the color sequence is the same, thereby improving the dynamic color switching effect of the target model and enhancing the user experience.

[0121] In the above optional embodiment, the frame color value corresponding to each frame of the dyeing area is obtained according to the first corresponding relationship and the second corresponding relationship, so that the dyeing area can be rendered frame by frame according to the frame color value corresponding to each frame, thereby improving the dynamic color change effect of the dyeing area.

[0122] Step S108 , dynamically rendering the dyed area according to the frame color value corresponding to each frame to generate a target model with dynamically changing colors.

[0123] In an exemplary application, such as Figure 6 As shown, the frame color value of each frame of the dyeing area 1 can change with the number of frames. The dyeing area 1 includes the following sub-partitions: sub-partition A2, sub-partition B1, and sub-partition C2. The RGB color value of the dyeing area 1 at 0 frames is orange (237, 125, 49), the RGB color value of the dyeing area 1 at 30 frames is blue (91, 155, 213), and the RGB color value of the dyeing area 1 at 60 frames is orange (237, 125, 49). According to Figure 6The frame color value corresponding to each frame shown dynamically renders the dyeing area, so that the color of the dyeing area 1 changes from orange to blue at 0-1s, and then changes from blue to the initial color (orange) within 1-2s. The dyeing area 1 can cycle this dynamic color change process. Correspondingly, the color changes of the sub-areas corresponding to the dyeing area 1, that is, the sub-area A2, the sub-area B1, and the sub-area C2 are the same as those of the dyeing area 1.

[0124] In some embodiments, multiple dynamic color change schemes can be applied to the target model. When previewing the effects of different color schemes, there is no need to switch back and forth multiple times to preview the color of the target model. The corresponding dynamic color change scheme can be directly pulled from the server to automatically perform dynamic color change operations on the target model.

[0125] In an optional embodiment, if Figure 7 As shown, the method also includes:

[0126] Step 700, obtaining the real-time display frame rate and the number of dynamic color objects rendered in the target model displayed on the same screen;

[0127] Step 702: adjusting the number of dynamic color objects rendered in the target model according to the real-time display frame rate so that the display frame number is a preset value.

[0128] The more dynamic color objects are rendered in the target model displayed on the same screen, the lower the frame rate of the game will run. For example, when the number of dynamic color objects rendered is 1, the frame rate of the game can be 60, and when the number of dynamic color objects rendered is 5, the frame rate of the game may be reduced to 30 frames. In order to keep the frame rate stable, the number of dynamic color objects rendered in the target model displayed on the same screen can be adjusted. Exemplarily, the changes in the game running frame rate can be monitored in real time. When the frame rate is reduced, certain effects can be turned off, that is, the number of dynamic color objects rendered in the target model is reduced, so that the frame rate remains stable.
