I'm working on an axe. I've modelled the axe and am working on texturing it. I unwrapped the texture and inserted a picture into the UV image editor and made the mesh fit the picture. The only problem is there is a white gap in the texture, and I want to clone part of the texture to the white gap. I've seen this done on youtube with a texture painting tool or something like that, but when I try it, it doesn't seem to work.
Here is a screenshot of it
Thanks to anyone that replies :D
