I use the Gimp for creating the textures that I use in Blender. My problem is I don’t know how to create a good pattern for a repeating texture.
I have seen some paint programs where you can activate a setting, and then be able to paint all the way to one edge and have your cursor appear on the other side of the canvas. This allows you to create a pattern easily.
Does the Gimp have a feature like this one?
