I'm really having fun with this tool. The only feature I think it's missing is layers. Any chance that's in the works?
Sorry, currently not. It was never planned to be so complex. I just wanted to make a tool to create easy & fast PBR-Material Pixel-Textures. ^^
But I noticed this already, however with my current available amount of time I have on the side of my main job, which is less. I can't make any promisses for this. I would need to rewrite a lot of code.
