AssetPostprocessor.OnPreprocessMaterialDescription(MaterialDescription,Material, AnimationClip[])

参数

描述

将此函数添加到子类中，以便在导入 ModelImporter 时创建新材质时接收通知。

仅当您将 ModelImporter.materialImportMode 设置为 ModelImporterMaterialImportMode.ImportViaMaterialDescription 时，Unity 才会调用此函数。此函数让您在模型导入过程中控制材质属性和动画。MaterialDescription 结构包含导入文件中的所有材质数据。您可以使用它来填充材质和动画片段。
