I'm making room models in Blender for a friend, and I generally send him the .fbx and textures. I noticed recently he hadn't followed my video to apply the textures I sent correctly, and got to thinking: Can I open an fbx in Unity locally, set up the textures, save a prefab and email / Google drive him a prefab to load in his project so he doesn't have to worry setting it up? I see in this link that prefabs are good for various scenes within a project, but I'm curious how hard they are to share between projects (ie. different engine versions etc). Thanks for any tips.
