 The material list is a text file, one material per line, saved alongside the Urho3D model. It is used by the scene editor to automatically apply the imported default materials when setting a new model for a StaticModel, StaticModelGroup, AnimatedModel or Skybox component, and can also be manually invoked by calling \ref StaticModel::ApplyMaterialList "ApplyMaterialList()". The list files can safely be deleted if not needed.
