Hi everyone!
I made a tool for making a shading map from multiple PBR textures (met/spec/etc). I originally made this for importing megascans into unigine but it ended up becoming quite helpful for other stuff too.
Hope it helps someone :D
Also it's completely free and open-source, use it any way you wish!
