First things first, we need to finish the physics, then take care of the object loader (I posted one above, you better take a look at that zero because I have no idea how it works).
Awwww, C# again... i can see it is capable of importing 3D models "as is" in fly (that means out of my range of understanding ). That's why I thought about avoiding that and making of something that would be capable of loading "prefabs" in fly as they're already ready to use (I don't have to do anything else with it after loading it, except for placing it somewhere). Prefabs can be done in Unity itself. Time will show what I'll choose
What are prefabs?
