[0001] This disclosure relates to the field of computer technology, and more particularly to a material processing method, apparatus, electronic device, storage medium, and program product. Background Technology

[0002] With 3D technology now widely applied in film and television production, virtual simulation, digital twins, and many other fields, material processing of 3D models has become a core element in shaping the realism and artistic expression of virtual worlds. Precise material configuration allows models to exhibit realistic physical properties, such as the luster of metal and the texture of fabric, thereby meeting the high-quality presentation needs of various industries for 3D scenes and models.

[0003] In related technologies, the material processing methods for 3D models are often customized around the specific needs of a project. However, when project requirements change, such as when transitioning from one project to another, the entire material processing workflow becomes highly dependent on manual operation by designers. They need to rely on their own experience to analyze each parameter of the material one by one, and then manually adjust it according to the expected effect of the new project. This not only consumes a lot of time and energy, but also, due to the limitations of manual operation, it is difficult to quickly and accurately meet the material requirements of the new project, resulting in low overall efficiency. Summary of the Invention

[0004] This invention provides a material processing method, apparatus, electronic device, storage medium, and program product to automate and intelligently convert materials, enabling rapid and accurate processing of 3D model materials. This meets the diverse material requirements of different projects and achieves the technical effect of efficient, accurate, and flexible processing of 3D model materials.

[0012] The third module is used to generate a second material with the same physical characteristics as the first material based on the first texture channel information and the second texture channel information.

[0013] According to another aspect of the present invention, an electronic device is provided, the electronic device comprising:

[0014] One or more processors;

[0015] Storage device for storing one or more programs.

[0016] When one or more programs are executed by one or more processors, the one or more processors implement any of the material processing methods described in the embodiments of this disclosure.

[0017] According to another aspect of the present invention, a computer-readable storage medium is provided, which stores computer instructions for causing a processor to execute and implement any of the material processing methods of the present invention.

[0019] The technical solution of this disclosure involves determining a first 3D model, which includes a first material configured according to the material requirements of a first project, and identifying the material object to be processed. It acquires the first texture channel information corresponding to the first material and at least the second texture channel information corresponding to the project material used in the second project, defining the channel information of the first material and the requirements of the new project for the material channels.

In this process, there is no need for manual adjustment of parameters one by one, greatly saving manpower and time costs and improving the efficiency and accuracy of material processing. The technical solution of this disclosure solves the problem in the prior art where material processing heavily relies on manual operation when the material requirements of a 3D model project change, resulting in low efficiency and difficulty in accurately meeting the material requirements of the new project. It achieves automation and intelligence in material conversion, enabling rapid and accurate processing of 3D model materials, thereby meeting the material needs of diverse application scenarios in different projects, and achieving the technical effect of efficient, accurate, and flexible processing of 3D model materials.

[0039] Figure 1 This is a flowchart illustrating a material processing method provided in an embodiment of this disclosure. This embodiment is applicable to situations involving material processing. The method can be executed by a material processing device, which can be implemented in hardware and / or software and can be configured in electronic devices such as computers or servers. Figure 1 As shown, the method in this embodiment includes:

[0040] S110. Determine the first three-dimensional model, wherein the first three-dimensional model includes a first material configured according to the material requirements of the first project.

[0041] In this embodiment of the disclosure, in a 3D model project, the materials of the 3D model need to be configured according to the material requirements of the second project. However, the existing materials of the 3D model are configured according to the material requirements of the first project, which are different from the material requirements of the second project. Therefore, if the existing materials are directly applied in the project, the 3D model will not be able to present the expected visual effect. It can be understood that the material requirements of the first project can be understood as the material requirements of the first 3D model in the first project; the material requirements of the second project can be understood as the material requirements of the first 3D model in the second project. Here, the first project and the second project are 3D model projects with different material requirements.

[0042] To ensure that materials accurately adapt to project requirements, enabling the 3D model to achieve the same rendering effect as when using existing materials, if the material of a certain 3D model needs to be processed, this 3D model can be used as the first 3D model. In this embodiment, the first 3D model can be a 3D mesh model or a 3D point cloud model. For existing materials applied to the first 3D model, if the material does not match the project requirements, and if the material needs to be processed quickly to meet the material project requirements, this material can be used as the first material. In this embodiment, the first material can be understood as the material that needs to be processed at the current moment for the materials applied to the 3D model. The number of materials applied to the first 3D model can be one, two, or more. In practical applications, the number of materials applied to the first 3D model is usually multiple.

[0043] In this embodiment, the material requirements for the first project specify the first texture channel information corresponding to the project material used in the first project. The first texture channel information can be understood as the texture channel information corresponding to the first material of the first 3D model. To ensure the model exhibits the desired material effect, the texture channel information includes a channel identifier and a texture type identifier to reflect the mapping relationship between textures and material channels. In simpler terms, it indicates which textures are assigned to which channels of the material. It is understood that the channel identifier can be used to distinguish different material channels. The texture type identifier can be used to distinguish different types of textures. In this embodiment, a mapping table is used to define the correspondence between different types of material channels (such as diffuse, normal, etc.) and specific textures. A texture is a file that stores image data and is used to define the surface properties of the material (such as color, bump, transparency, etc.). In this embodiment, a texture can include at least one type of base color texture, ambient occlusion texture, normal texture, roughness texture, and metallic texture. In practical applications, a material of a 3D model typically corresponds to at least two types of textures. Material channels can be used to receive texture data and control rendering effects. Each channel corresponds to a surface property of the material (such as color, bump, transparency, etc.). Optionally, material channels may include at least one of diffuse channels, normal channels, roughness channels, metallicity channels, and transparency channels. In practical applications, 3D models typically have multiple material channels.

[0044] For example, the first material of the 3D model includes 5 channels, labeled T1, T2, T3, T4, and T5. The corresponding textures for this material can include 5 different types of textures, labeled M1, M2, M3, M4, and M5. The correspondence between texture type labels and channel labels in the texture channel information of this material can be as follows: channel T1 corresponds to texture M1, channel T2 corresponds to texture M2, channel T3 corresponds to texture M3, channel T4 corresponds to texture M4, and channel T5 corresponds to texture M5.

[0045] Specifically, the 3D model to be processed, i.e., the first 3D model, is determined. Then, the material of the first 3D model can be determined. In one optional embodiment, the first 3D model may have only one material, and the material to be processed is determined as the first material of the first 3D model. In another optional embodiment, the first 3D model may have multiple materials. Determining the material to be processed of the first 3D model may include: traversing the existing materials corresponding to the first 3D model, and using the currently traversed material as the material to be processed of the first 3D model. Then, the texture channel information corresponding to the material to be processed, i.e., the first texture channel information, can be obtained.

[0046] In this embodiment of the disclosure, determining the first material of the first three-dimensional model may include: displaying a first interface; wherein the first interface includes a model identifier of at least one second three-dimensional model; in response to an identifier selection operation for the model identifier, determining a three-dimensional model to be materialized based on the identifier selection operation, and performing material traversal processing on the three-dimensional model to be materialized to determine the first material of the first three-dimensional model.

[0047] The first interface can be understood as an interface used to present the model identifier of the second 3D model. In this embodiment, the second 3D model can be understood as a 3D model whose pre-set model material is not compatible with the material requirements of the current project. The number of second 3D models can be one, two, or more. In practical applications, the number of second 3D models is usually multiple. The model identifier can be used to distinguish different 3D models. The model identifier can be visualized through text information and / or image information. When the model identifier includes text information, the model identifier can include at least one of model number and model name. When the model identifier includes image information, the model identifier can be a two-dimensional icon (such as a model thumbnail) or a 3D model preview image. In this embodiment, the identifier selection operation can be understood as a trigger operation (e.g., a click trigger operation) used to select the model identifier of the second 3D model in the first interface.

[0048] In this embodiment, there are various ways to display the first interface, and no specific limitation is made herein. For example, after the game engine runs, a first interface including model identifiers of multiple second 3D models is displayed. Alternatively, a second interface can be displayed after a preset application runs; wherein the second interface includes a first control, the first control being used to display the first interface including model identifiers of multiple second 3D models. The first interface is displayed in response to a control trigger operation on the first control.

[0049] In this embodiment of the disclosure, determining the 3D model to be processed based on the identifier selection operation, and performing material traversal processing on the 3D model to determine the first material of the first 3D model, may include: determining the selected 3D model, i.e., the 3D model to be processed, based on the identifier selection operation. Then, the existing materials applied to the 3D model can be traversed to determine the currently traversed material. Thus, the currently traversed material can be used as the first material of the first 3D model.

[0050] S120. Obtain the first texture channel information and the second project material requirements corresponding to the first material, wherein the second project material requirements are used to specify at least the second texture channel information corresponding to the project material used in the second project.

[0051] In this embodiment, the material requirements for the second project include at least the second texture channel information corresponding to the project materials to be used in the 3D model of the second project. The second texture channel information can be understood as the texture channel information pre-defined for the materials of the 3D model in the project specifications established beforehand for the materials of the 3D model in the second project. It should be noted that the project specifications, i.e., the pre-defined development rules at the beginning of the project, must be followed by relevant technical personnel in their design. Following unified specifications helps avoid differences affecting work efficiency during team collaboration. However, the 3D model to be processed often cannot be directly applied to the project because the texture channel information of the materials in the specifications differs from that in this project specification. In this embodiment, the second texture channel information is different from the first texture channel information. Specifically, the number of channels in the second texture channel information is different from the number of channels in the first texture channel information; and / or, the mapping relationship between the texture type identifier and the channel identifier in the second texture channel information and the first texture channel information is different. Optionally, the number of channels in the second texture channel information is less than the number of channels in the first texture channel information. Or, the number of channels in the second texture channel information is more than the number of channels in the first texture channel information. Alternatively, the number of channels in the second texture channel information is the same as that in the first texture channel information, but the mapping relationship between the texture type identifier and the channel identifier is different.

[0052] Continuing with the previous example, the material required for the 3D model in the project includes three channels, labeled T6, T7, and T8. Channel T6 corresponds to texture M1, and channel T7 corresponds to the texture generated based on textures M2 and M3. Figure 6 Correspondingly, channel T8 corresponds to the texture generated based on textures M4 and M5. Figure 7 correspond.

[0053] S130. Based on the first texture channel information and the second texture channel information, generate a second material with the same physical characteristics as the first material.

[0054] In this embodiment, the second material can be understood as a material with the same physical characteristics as the first material, obtained based on the first and second texture channel information. The second texture channel information can be understood as the texture channel information of the second material. In this embodiment, the second texture channel information and the first texture channel information are identical. In this embodiment, a second material that meets the project requirements is generated, and this second material has the same physical characteristics as the first material. Therefore, the rendering effect of applying the second material to the 3D model is the same as the rendering effect produced when the first material is applied to the same 3D model.

[0055] In this embodiment, a texture corresponding to the first material is determined based on the correspondence between materials and textures. Therefore, based on the first and second texture channel information, the texture corresponding to the first material can undergo texture channel recombination processing to obtain a processed texture. Furthermore, based on the processed material, a second material with the same physical characteristics as the first material and texture channel information as the second texture channel information can be obtained. For example, the textures corresponding to the first material of the 3D model include a base color texture, an ambient occlusion texture, a normal texture, a roughness texture, and a metallic texture. Depending on project requirements, the base color texture and the ambient occlusion texture can be recombinated into a single texture. Also, the normal texture, the roughness texture, and the metallic texture can be recombinated into a single texture.

[0056] In this embodiment of the disclosure, a second material with the same physical characteristics as the first material is generated based on the first texture channel information and the second texture channel information. This can improve the reusability of the 3D model and its existing materials in different projects, and avoid repetitive and time-consuming operations such as manually adjusting texture parameters and redrawing textures during the material processing.

[0057] Based on the above embodiments, after generating a second material with the same physical characteristics as the first material based on the first texture channel information and the second texture channel information, the method further includes: replacing the material of the three-dimensional model with the second material so that the three-dimensional model maintains the original physical rendering effect.

[0058] See Figure 2 The following example uses a mailbox model 200 as an illustration. The existing material 210 of this mailbox model 200 is instantiated based on the parent material A220. The material map 230 corresponding to the existing material 210 includes various types, specifically including a base color map 231, a normal map 232, a detail normal map 233, a roughness map 234, a detail roughness map 235, a metallic map 236, and an ambient occlusion map 237.

[0059] The project requirements necessitate that the 3D model utilize a second material, 250, instantiated from the parent material B240. This second material 250 supports setting two textures. To ensure the existing project model maintains its original rendering effect (e.g., ...), ... Figure 3 As shown in Figure 301, and by reusing existing model resources, in this embodiment of the disclosure, a "base color-ambient mask" figure 260 is generated by combining the base color figure 231 and the environment mask figure 237; and a "normal-roughness-metal" figure 261 is generated by combining the normal figure 232, the detail normal figure 232, the roughness figure 234, the detail roughness figure 235, and the metal figure 236. The "base color-ambient mask" figure 260 and the "normal-roughness-metal" figure 261 can then be set as two material maps of the second material 250. The material of the mailbox model is then replaced from the existing material 210 to the second material 250, and the rendering effect after the replacement is as follows. Figure 3 As shown in 302. It should be noted that parent material A220 and parent material B240 are inherited, that is, different subclasses of the same parent material.

[0060] As an optional implementation in this disclosure, in response to the generation event of the second material, the material of the first three-dimensional model in the project can be automatically replaced by the second material so that the first three-dimensional model maintains the original physical rendering effect, thereby realizing the automatic adaptation of the three-dimensional model material, improving project development efficiency and reducing development costs.

[0061] As another optional implementation in this disclosure, upon detecting the generation of a second material, a second control can be displayed; wherein the second control is used to replace the material of the first 3D model with the second material. In response to a control trigger operation on the second control, the material of the first 3D model is replaced with the second material. This approach provides an intuitive and convenient interaction method, enabling users to quickly and accurately perform material replacement operations according to their actual needs.

[0062] The material processing method in this embodiment can use a preset rendering engine to process the materials of 3D models that are not suitable for the project requirements, and can quickly generate materials that meet the project requirements. In other words, the preset engine can automatically generate a series of materials that meet the project requirements. Furthermore, the preset rendering engine provides operation controls that allow for convenient and quick replacement of the materials of a 3D model with a second material, realizing a batch one-click processing workflow and fully automated processing from material extraction and generation to material replacement.

[0063] The technical solution of this disclosure involves determining a first 3D model, which includes a first material configured according to the material requirements of a first project, and identifying the material object to be processed. It acquires the first texture channel information corresponding to the first material and at least the second texture channel information corresponding to the project material used in the second project, defining the channel information of the first material and the requirements of the new project for the material channels. Based on the first and second texture channel information, the material conversion and generation can be automatically completed, generating a second material with the same physical characteristics as the first material. In this process, there is no need for manual adjustment of parameters one by one, greatly saving manpower and time costs and improving the efficiency and accuracy of material processing. The technical solution of this disclosure solves the problem in the prior art where material processing heavily relies on manual operation when the material requirements of a 3D model project change, resulting in low efficiency and difficulty in accurately meeting the material requirements of the new project. It achieves automation and intelligence in material conversion, enabling rapid and accurate processing of 3D model materials, thereby meeting the material needs of diverse application scenarios in different projects, and achieving the technical effect of efficient, accurate, and flexible processing of 3D model materials.

[0064] Figure 4 This is a schematic flowchart illustrating another material processing method provided in this embodiment. The technical solution of this embodiment can be combined with other embodiments; for the same or related parts, they can be described in conjunction with the descriptions of other embodiments, and will not be repeated here. Figure 4 As shown, the method in this embodiment may specifically include:

[0065] S410. Determine the first three-dimensional model, the first three-dimensional model including a first material configured according to the material requirements of the first project, the first material being a PBR material.

[0066] PBR (Physically Based Rendering) is a rendering technique that generates images by simulating the interaction between light and materials in the real world.

[0067] S420. Obtain the first texture channel information and the second project material requirements corresponding to the first material, wherein the second project material requirements are used to specify at least the second texture channel information corresponding to the project material used in the second project.

[0068] S430. Determine the physically based rendering (PBR) texture of the first material.

[0069] In this embodiment of the disclosure, the physically based rendering (PBR) map may include at least one of a base color map, an ambient occlusion map, a normal map, a roughness map, and a metallicity map. Specifically, multiple physical properties of the first material (e.g., metallicity, roughness, transparency, color, etc.) are determined. Thus, a physically based rendering (PBR) map corresponding to each physical feature can be obtained based on these physical properties, i.e., the physically based rendering (PBR) map of the first material.

[0070] In this embodiment of the disclosure, determining the physically based rendering (PBR) map of the first material may include: assigning the first material to a material processing object of a pre-created patch model; and extracting PBR attributes of the first material by calling the program data corresponding to the material processing object to determine the physically based rendering (PBR) map of the first material.

[0071] In this embodiment, the patch model is a three-dimensional model with negligible thickness, and its width and height can be set according to actual needs, without specific limitations. The material processing object can be understood as a feature used to obtain and separate the PBR attribute information of the first material, ensuring the feasibility of subsequent texture information reassembly and adaptation to the project's material texture. Optionally, the material processing object can be a material merging processing object provided for the three-dimensional model in a preset engine. PBR attributes are the physical properties of the first material. In this embodiment, PBR attributes can include one of the following attributes: metallicity, roughness, transparency, and color. The program data corresponding to the material processing object can be program data pre-written according to project requirements for processing the first material.

[0072] Specifically, a material processing object for a pre-created patch model is used. The first material is assigned to the material processing object. Then, using the program data corresponding to the material processing object and leveraging the material merging function of the material processing object, PBR attributes of the first material are extracted to obtain the PBR attributes of the first material, i.e., the physical properties of the first material. This allows the generation of a physically based rendering PBR map corresponding to the physical attributes, i.e., the physically based rendering PBR map of the first material.

[0073] Compared to using the material processing object of the first 3D model itself, in this embodiment of the disclosure, using the material processing object of the planar model can avoid the need for texture rearrangement of the mesh when using the material processing object of the first 3D model itself for material processing (see...). Figure 5 This ensures that the generated texture map still conforms to the original texture map distribution (see...). Figure 6 This achieves the effect of material baking. Furthermore, by using the material processing object of the first 3D model itself, even if only one material is processed, the textures are rearranged. If this result is used to generate a texture, the generated texture will no longer fit the first 3D model, resulting in incorrect material results. This method can only use the processed 3D model to replace the existing 3D model; it is only suitable for 3D models using a single material and cannot adapt to 3D models with multiple materials.

[0074] In this embodiment, the material processing object of the planar model is used to process each material of the first 3D model, decoupling the material processing from the 3D model so that the processing does not affect the first 3D model. Furthermore, since the planar model itself is simply a square formed by two triangles joined together, its texture effectively fills the [0..1] space. Therefore, rearranging the texture information during material processing will not affect the texture, and the extracted texture information will not be reorganized into pixel positions. The resulting texture perfectly matches the texture arrangement and can be used directly, ensuring the feasibility of using the material merging characteristics of the material processing object to adapt the existing materials of the first 3D model to project materials.

[0075] In the embodiments disclosed herein, such as Figure 7 As shown, after the PBR attribute of the first material is extracted, the PBR attribute can also be displayed in the third interface to ensure the feasibility of subsequent texture information reorganization and adaptation to the project material texture.

[0076] S440. Based on the first texture channel information and the second texture channel information, perform texture channel recombination processing on the physically based rendering (PBR) texture to obtain the recombined texture.

[0077] Specifically, based on the mapping relationship between channel identifiers and texture type identifiers in the second texture channel information, and the mapping relationship between channel identifiers and texture type identifiers in the first texture channel information, the physically based rendering (PBR) texture is subjected to texture channel reassembly processing to obtain the reassembled texture. In this embodiment of the disclosure, the correspondence between channel identifiers and texture type identifiers in the second texture channel information can be one-to-one, one-to-many, or many-to-one.

[0078] S450. Based on the recombined texture, a second material with the same physical characteristics as the first material is obtained. The second texture channel information of the second material is different from the first texture channel information.

[0079] Specifically, the recombined textures are subjected to feature extraction and stitching to obtain fused features. Then, a second material with the same physical characteristics as the first material can be generated based on these fused features.

[0080] Based on the above embodiments, before generating a second material with the same physical characteristics as the first material based on the first texture channel information and the second texture channel information, the method may further include: determining first texture attribute information of the second material. The first texture attribute information can be understood as the texture attribute information of the second material. In this embodiment, the first texture attribute information may include a first texture resolution and / or a first texture aspect ratio.

[0081] The first texture resolution can be understood as the resolution of the first texture corresponding to the second material. The first texture can be understood as the texture corresponding to the second material. Optionally, it can be a texture resolution pre-set for the material to be generated, or it can be the default texture resolution of the first material; etc. In this embodiment, the first texture resolution can be set or adjusted according to project requirements, and is not specifically limited here. The aspect ratio of the first texture can be understood as the aspect ratio of the first texture corresponding to the second material. Optionally, the aspect ratio of the first texture can be the aspect ratio of the texture corresponding to the first material. It is understood that the aspect ratio is the ratio of the width to the height of the texture.

[0082] Accordingly, obtaining a second material with the same physical characteristics as the first material based on the reconstructed texture may include: performing texture processing on the reconstructed texture based on the first texture attribute information to obtain a processed texture, and obtaining a second material with the same physical characteristics as the first material based on the processed texture. In one embodiment, the first texture attribute information includes a first texture resolution, and performing texture processing on the reconstructed texture based on the first texture attribute information to obtain a processed texture may include: processing the reconstructed texture into a texture with a resolution equal to the first texture resolution. The first texture attribute information includes a first texture aspect ratio, and performing texture processing on the reconstructed texture based on the first texture attribute information to obtain a processed texture may include: processing the reconstructed texture into a texture with an aspect ratio equal to the first texture aspect ratio.

[0083] To facilitate viewing and adjusting the first texture attribute information, in this embodiment of the disclosure, the first texture attribute information can be displayed once obtained. Based on this, the first texture attribute information can be flexibly and conveniently adjusted according to actual needs. Optionally, the first texture attribute information includes a first aspect ratio; displaying the first texture attribute information may include displaying the first aspect ratio. Specifically, displaying the first aspect ratio may involve determining the aspect ratio of the texture corresponding to the first material and using that aspect ratio as the first aspect ratio.

[0084] Based on the above embodiments, before determining the first texture attribute information of the second material, the method may further include: displaying a default texture resolution corresponding to the first material; obtaining a modified texture resolution in response to a modification operation on the default texture resolution; and obtaining the first texture attribute information for the second material based on the modified texture resolution.

[0085] The default texture resolution can be understood as the resolution (e.g., 1024×1024) pre-set for the texture to be generated for the first material. In this embodiment, the default texture resolutions for different materials can be the same or different. Specifically, the default texture resolution corresponding to the first material is determined. The default texture resolution is displayed. Upon receiving a modification operation for the default texture resolution, the modified texture resolution can be obtained. The modified texture resolution can then be used to update the first texture attribute information for the second material to obtain the updated first texture attribute information. This process allows the default texture resolution to be adjusted according to actual needs, accurately adapting to different detail requirements or performance limitations, avoiding excessive resource consumption or loss of detail due to a fixed resolution, and improving the flexibility and practicality of material generation.

[0086] Based on the above embodiments, the method may further include: displaying second texture attribute information of the first material. The second texture attribute information can be understood as the texture attribute information of the first material. In this embodiment, the second texture attribute information may include a second texture resolution and / or a second texture aspect ratio.

[0087] In this context, the second texture resolution can be understood as the resolution of the second texture corresponding to the first material. The second texture can be understood as the texture corresponding to the first material. In one embodiment, if the first material corresponds to only one texture, the second texture corresponding to that first material can be that same texture. Therefore, the second texture resolution is the resolution of the texture corresponding to the first material. In another embodiment, if the first material corresponds to multiple textures, the second texture corresponding to the first material can be the texture with the highest resolution among those corresponding to the first material. In this case, the second texture resolution can be the resolution of the texture with the highest resolution.

[0088] In this embodiment, the aspect ratio of the second texture can be understood as the resolution of the third texture corresponding to the first material. The third texture can be understood as the texture corresponding to the first material. In one embodiment, if there is only one texture corresponding to the first material, the third texture corresponding to the first material can be that same texture. Therefore, the aspect ratio of the second texture is the aspect ratio of the texture corresponding to the first material. In another embodiment, if there are multiple textures corresponding to the first material, the third texture corresponding to the first material can be the texture with the largest aspect ratio corresponding to the first material. In this case, the aspect ratio of the second texture can be the aspect ratio of the texture with the largest aspect ratio. In this embodiment, the third texture and the second texture can be the same texture or different textures.

[0089] In this embodiment of the disclosure, the interface displaying the second texture attribute information and the interface displaying the first texture attribute information can be the same interface or different interfaces. See also Figure 8 The second texture resolution, the first texture resolution, and the first texture aspect ratio are displayed on the same interface, namely the fourth interface 80. This fourth interface 80 includes a first area 81, a second area 82, and a third area 83. The first area 81 is used to display at least one second texture resolution. The second area 82 is used to display at least one first texture resolution. The third area 83 is used to display at least one first texture aspect ratio. Furthermore, in this embodiment, the interface for displaying the second texture attribute information and the first texture attribute information may also include a preset control, so that upon receiving a control trigger operation on the preset control, the second texture attribute information and the first texture attribute information are displayed on the fourth interface.

[0090] The technical solution of this disclosure embodiment determines the physically based rendering (PBR) texture of the first material; performs texture channel recombination processing on the physically based rendering (PBR) texture based on the first texture channel information and the second texture channel information to obtain a recombined texture; and obtains a second material with the same physical characteristics as the first material based on the recombined texture, thereby realizing the function of obtaining a second material through texture channel recombination.

In this process, no manual adjustment of parameters is required, greatly saving manpower and time costs and improving the efficiency and accuracy of material processing. This technical solution solves the problem in the prior art where material processing heavily relies on manual operation when the material requirements of a 3D model project change, leading to low efficiency and difficulty in accurately meeting the material requirements of the new project.
