Hi . This is probably a basic question but I was wondering... I have a prefab which I open with Prefab mode. Then with an editor tool I assign a sharedMesh and a Texture2D that are instanced and not saved to disk. In a scene, these would get serialized in the scene since they are not references in the project view. But in prefabs, when you get out of the prefab mode after saving these changes, these instances of the mesh or texture are lost and None is shown in the instanced prefab in the scene that I just edited. How do I make them save? Is it possible to assign instances of object classes without having references in the Project on prefabs?
