Anyway to load non-resource 3D models? #2

Hey, been playing around with mod development having a great time. Though I have ran into trouble attempting to load in a 3D model which is not included in the Unity project's resource.asset file. Although I know that this is more of a Unity modding issue than an issue with your code I was wondering if you had put any thought into how to import and load arbitrary 3D models into the game at runtime. I haven't had any luck with some of the fbx importer code floating around on Github. Thanks for the help!
