actually as far as refs go ive mostly been using your screens of your car. i figure why not. it works. Ive noticed a few small differences however between some of my refs which is annoying.
Did you model each section individually(like bumpers, side skirts so on or as one mesh. I ask because id ont see the seam for your rear bumper to trunk to quarter panel area. Or do you plan on separating them after?
Ill throw some wips on my thread now.
