ArmorPaint - 3D PBR texture painting

This software is for texture painting 3D models, it is a standalone software, so not just a texture generator like normal map generators. I have not tested it, but it was suggested by someone from our development community and I kept it as a bookmark to have a free open source alternative program to texture paint 3D models with the latest PBR stuff. Blender also has texture painting features, but I usually later edited the textures in Gimp and a normal map generator as well, so maybe this tool could offer a better workflow.
