Update coming soon. I have fixed lighting problems, some mistakes in the model, and also made it a little more optimized (Now there are roughly 800 shapes comparing to original 1000+). I will also add new cars (Textures). Here is a little sneak peak:
Lets say, the cockpit console is a block 20 by 10, you replace it with a shapebox of 200 by 100 (same proportions). Than you resize the shapebox down to 20 by 10 by editing the corners. the texture size will remain 200 x 100 and placed on the smaller shapebox.
