Well, how do you paint over the skin while keeping the textures? I thought using the paintbrush with the grain merge would work, but it doesn't work now. It did what it was supposed to before. I guess the reults we mixed at best with it. If I wanted to paint the tugboat hull black, it would darken it, but if I chose the white color and wanted to make a line it would just lighten the black somewhat. I've been trying to do the tugboat to try and get a feel for skinning and how to use The Gimp. So far, neither seems to be working.
How do you change things like get rid of rust, modify it, or create more?
