Recentely I did some import operator for PBR textures, and realized it is quite simillar to this one in node wrangler.
I wanted to extend
with ao and alpha textures. As well to cleanup bump and normal relations (as a separate input textures).
It is based on nice presentation
Additionally, there are variation in spec/roughness ranges for almost every PBR texture source, so I've added adjust layer of nodes, for ease of use.
I've created this task to ask you all if i can update those changes. It is my first commit here for other author code.
