MatLayer

MatLayer is a free and open-source libre add-on that drastically speeds up and simplifies the material editing workflow by providing a wrapper user interface for Blender's vanilla material nodes. You can use MatLayer to make optimized, professional quality materials and textures for game engines, VRChat, still renders, movies and more.

I've invested over 2000 hours over the past 3 years in designing, programming, researching, testing and making assets for MatLayer, so there will be a great, free 3D material editing solution available, and everyone will have the freedom to create.
