I am a complete newb at this and am trying to change the coloring on this dog (with permission from the original creator) to match mine and mod it into Skyrim, but when I try to paint it in texture paint I get the bit below.
It doesn't happen if I use Gimp to edit the image and then add it back on, but then I can't exactly see what part I am coloring.
How to go about this, preferably while keeping the furlike texture?
