I’m currently looking for alternatives to GIMP for texturing. I need a good Open Source+Free software that is capable of clone-brushing from multiple layers at once unto new corresponding layers.
Let’s say I have a texture 1024*1024 of a brick wall, which I’ve created a normal map and a displacement map.
Then I import the Diffuse, Normal and Displacement into the software’s different layers, each on their own layers.
What I want to do is to create 3 new layers (CloneDiffuse, CloneNormal, CloneDisp) and be able to extend and clone brush a larger texture, lets say 2048*2048 using a Clone Brush and it will clone from all the other layers, placing the cloned Normal Map in CloneNormal-layer, Displacement in CloneDisp etc.
Is there any free software that can do this? GIMP can’t.
