public bool SearchAndRemapMaterials (ModelImporterMaterialName nameOption, ModelImporterMaterialSearch searchOption);


nameOption The name matching option.
searchOption The search type option.


bool Returns false if the source file is empty or invalid. Returns true otherwise.


Search the project for matching materials and use them instead of the internal materials.

Unity uses the naming convention specified by nameOption to find and match Material assets in your project and maps them to the model. Use the search option to specify if you want the search to be done project wide, locally or recursive up from the model's location.
