I noticed while playing with the car designer, that after you have tweaked your body design and moved on to add fixtures, there is no way to go back and edit the body without removing all of the fixtures.
It would be nice to be able to modify the body after leaving its page.
Yeah I agree, unfortunatly moving the shape of the car body underneath the stamped fixtures causes a lot of problems, we are looking into a way of doing it, but it might not be possible.
Also, any way to layer the fixtures so you can select diffrent ones, its anoying to have to slap lights on the quarter panels to put them over cutouts etc.
