The game mesh is all prepared now. I still need to add the wheels, tyres, interior details and whatever else. There was a problem with the extraction where the wheels didn't extract with the rest for some reason. I'll be doing those from scratch soon. I could still use some help with police car interiors, but I'll be googling that later too. Here's a pic then of the mesh as it is now. The faces are double sided just for the purpose of the pic.
