Description

Technical Field

[0001] The present invention relates to the technical field of three-dimensional model conversion, and specifically provides a system and conversion method for intelligent replacement of material modules. Background Art

[0002] With the wide application of 3D models and their materials in the fields of games and virtual reality, how to efficiently convert 3D assets in different platforms and software, especially the conversion between Blender and UE, has become an important technical challenge. Traditional conversion methods often rely on manual operations, which are not only cumbersome but also error-prone, resulting in low work efficiency. To solve this problem, a conversion method supporting intelligent replacement of material modules is proposed. This method can efficiently convert Blender models and their materials into the format required by UE through automated and intelligent strategies, greatly improving work efficiency and conversion success rate.

[0003] Existing 3D model conversion technologies have multiple defects. First, traditional methods often rely on manual intervention, and errors are likely to occur when reading, classifying, and mapping models and their materials, resulting in unsatisfactory final effects. Second, existing technologies are not flexible enough in handling advanced features of material nodes and cannot automatically identify and convert complex material attributes, restricting the visual effects of models. In addition, existing methods lack effective error detection and repair mechanisms. When problems occur during the conversion process, manual intervention is often required, which further reduces work efficiency. Therefore, there is an urgent need for an automated and intelligent conversion method to solve these technical bottlenecks.

[0004] The conversion method supporting intelligent replacement of material modules proposed in this solution significantly improves the efficiency and accuracy of model conversion through a comprehensive automated process. This automated processing reduces the need for manual intervention and the probability of errors. This solution not only improves conversion efficiency but also enhances the quality of models, providing a more reliable solution for the management and use of 3D assets. Summary of the Invention

A conversion system for supporting intelligent replacement of material modules, which is applied to a conversion method for supporting intelligent replacement of material modules according to any one of claims 1-6, and is characterized in that, Including: Data reading and processing module: Parse the Blender model file, identify the positions of each data block, crop and extract important data according to the offset and size of the data block, classify and label the extracted data, compress the data module, and store it in a suitable memory area; Intelligent material conversion module: Obtain all the material node attribute data in the Blender model, extract the attribute data of the material nodes, automatically map them to the material nodes of UE, create appropriate texture resources for UE according to the UV channel information, and support virtual texture streaming; Dynamic mapping and segmentation processing module: Create the mapping relationship of the attribute data of the Blender model material nodes, divide the model into sub-modules according to the material type, process each sub-module one by one, parse the attribute data of each material node, and convert it into the material parameter format required by UE; Problem detection and repair module: Automatically detect problems in the Blender model, execute intelligent compatibility repair strategies, and use methods such as automatic triangulation and closing non-manifold edges to repair geometry problems, reallocate UV space, and repair UV stretching problems; Error detection and fault tolerance repair module: Real-time detect potential errors during the conversion process, and execute fault tolerance and adaptive repair strategies, automatically enable alternative solutions, generate backup material instances or use default textures to fill, check the UV channels of the model, and automatically generate a default UV unwrap if missing; Data saving and integrity verification module: Save all modules as UAsset files, automatically bind them to the specified path in the UE project, and perform integrity verification to ensure that the converted files meet the requirements of UE.
