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

参数

描述

Add this function to a subclass to recieve a notification when a new material is created during the import of a ModelImporter.

Unity only calls this function if you set ModelImporter.materialImportMode to ModelImporterMaterialImportMode.ImportViaMaterialDescription. This function gives you control over material properties and animations during the model import process. The MaterialDescription structure contains all the material data from the imported file. You can use it to populate the material and animation clips.

            // Assign the texture to the material.
            material.SetTexture("_MainTex", textureProperty.texture);
