That's sounds pretty bad but, what they hey it's just a proof concept till we can figure things out so it doesn't really matter.
We HAVE to use real car names. IDK if you remember the old list of cars to be in the game form way back when years ago. For SR3 to really work it ha to be real cars.
EDIT: I was able to import my garage 3Ds file under "prefabs" "environment" obviously i don't know how to make it show up but, it does see all the little models that exist in my 3ds file so that's good/nice.
it would probably help if we properly understood file and project structuring. I see programers talking about it all the time on various projects on the internet, so i might assume or speculate that it's fairly important.
