AssetPostprocessor.OnPostprocessMaterial(Material)

説明

Add this function to a subclass to get a notification when a new Material is created during an import of a ModelImporter.

Use this method to modify the properties of newly created Material assets during import.

Note: This method is only called by the ModelImporter when the ModelImporter.MaterialImportMode option is set to ModelImporterMaterialImportMode.ImportStandard.

public class MakeMaterialsRed : AssetPostprocessor

    void OnPostprocessMaterial(Material material)
    {
