I recently tried a different approach to the AI generation. I uploaded a few pics of the truck when it was assembled and then directed the AI tool to make the changes that I wanted. It worked pretty good with a few minor glitches but I was able to see some changes that I may want to make.
Initially I thought that I wanted to simply use black bedliner in the bed instead of body paint but after seeing the rendering I don't care for it (although I wasn't going to bedline the top edge of the bed like the rendering).... the body color looks so much better. I also was able to direct AI to generate the truck in a different venue (in front of old gas stations).
I'll continue to play around with it from time to time to better dial-in what I want. I suggest you try it if you are trying to determine what looks good.
