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

Parameters

Description

Add this function to a subclass to recieve a notification when a material is imported from a Model Importer.

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.
