101. Determine the target model in Unreal Engine;

It can be understood that the subject of execution of the present invention may be an exporting device of a model file, and may also be a terminal or a server, which is not specifically limited here. The embodiment of the present invention is described by taking a server as an execution subject as an example.

In practical applications, generally 3dsmax can be directly exported to other DCC software. In this embodiment, the UE is mainly exported, because the UE project may be obtained from other studios or downloaded externally, and There is no 3dsmax source file, or there is a 3dsmax source file, but after entering UE, there is a secondary modification and the information of the original 3dsmax file is inconsistent, so it can only be exported from UE. When there is a 3dsmax source file, the modeling work of the 3D model is mainly done by the artist. The division is carried out on 3dsmax, and then the model is exported from 3dsmax to UE. In the current mainstream game development, the fbx is manually exported from 3dsmax, and then manually imported into UE, and then the relative position of the model is manually aligned and restored in UE. After the model imported into UE is assembled into a scene, it needs to be exported to DCC such as Maya and Blender for secondary editing. In this embodiment, the target model in Unreal Engine is created by an artist on 3dsmax It is obtained after modeling and imported into UE. In addition, when there is no 3dsmax source file, the target model in Unreal Engine is obtained from other studios or downloaded externally. This application does not make any reference to the source of the target model in Unreal Engine. limited.

In this embodiment, the texture file of each target model is determined in advance by texture drawing software, wherein the texture drawing software can be Substance Painter, Photoshop, etc., and the model file can be imported into the texture drawing software. For the target model, the server may generate several kinds of texture files for the model file in the texture drawing software in response to a texture drawing instruction for the model file of the target model. Here, the texture file may be a texture file with one or more attributes such as intrinsic color, roughness, metalness, normal, etc., which is determined based on the display effect of the target model. The texture drawing command is used to instruct the texture drawing software to generate corresponding texture files. Texture drawing software can generate texture files that meet the PBR (Physically-Based Rendering, based on physical rendering) standard, which can be easily exported as 3D model assets and imported into the rendering engine, which can greatly reduce the time cost of subsequent rendering to obtain virtual scenes. In 3dsmax After obtaining the model file and several texture files corresponding to the model file, the server can import each model file and its corresponding texture file into Unreal Engine.

In this embodiment, the model selection instruction is generated through the API and export interface settings in the Unreal Engine, and the server responds to the model selection instruction to determine all target models corresponding to the model selection instruction, and obtains the target model through the function mesh.static_mesh_component.get_materials The material information of the target model, and obtain the texture file of the target model based on the material information through the function material.texture_parameter_valUEs.
