Can you create your own paint job?
I want to know because I would like to create gp paint jobs.
You can create custom paint schemes with pretty much any image editing software like Photoshop, you just need to save/convert it to a .dds file for it to show up in game. A scheme also has to be downloaded by other people for them to see it in their game.
