I can't remember off the top of my head and I'm too lazy to open Krita to see what the dialogue box says x_x It was definitely doing (or not doing) something and I haven't done 2d digital art this entire year again and probably should just to test out the new version (I think it's gone up a couple of minor versions since I last used it x_x)
I have a Blender add-on for texture mapping these days ^_^
though I have to try out a new one as the one I have stopped working on the newest Blender and apparently stopped existing too
