I have a ship that uses uv editing to colour it.(dragging around the vertexs around a colour map. explained further in https://www.youtube.com/watch?v=1jHUY3qoBu8&feature=emb_logo at 2:20 - 3:20) When i export to unity its white, so i tried baking and using the png over the fbx in unity. The problem is, when i try to bake it the pic is black! i'll send the blend file once i figure it out. I will be eternally grateful to anyone who can solve my problem!!
