(I don't have any access to external programs, nor the patience or time to learn them. I want my Blender problems to stay in Blender.)
I have a Picture inside my UV Editor, and I wanted to know a way to apply a material, color, or paint to affect this image, or my mesh.
'This picture wraps around my barrel. I have cracks in the wood itself, and separating the individual planks. I want to apply 'black' to those cracks.'
I wish I could provide visuals, but apparently the 'Blender Forums' doesn't allow 2 images.
