So in this picture it shows at the top three circles, two being crossed out right now. What they do is allow you to be able to paint in different types, so like i mentioned before, height, colour, and glossiness. so I put some examples there beside the leaf.
Video for Reference:
For my leaf I want to export just the Diffuse map so I check only colour since I didnt add any other kind of map, most of my capstone will be mostly just painted with slight added height. You can choose what you want your model to be exported, fbx, obj, etc., and your textures end up being targas.
