I'm not really sure what software solution would be best, or if one even exists, but I have a car that I want to design the paint job for. It appears that Photoshop can import a 3D model and from there I can go ahead and paint it. What I'd like to be able to do is then convert the layers into stencils so that I can then actually paint my car.
I would prefer to work in a vector-based system and that seems to be more in the realm of Illustrator than Photoshop, but it's been a number of years since I have used either. Are there any programs that get me close? I'm more than fine to do some development on my end to close any holes between software solutions if I have to go through multiple pieces of software so long as I can automate the process of generating stencils after I complete the artwork.
