I started using that around a year ago to propel my importing pbr process so I can focus more so on the model and level/scene design. Lots of care went into a node starting point, as you can probably tell. It contains nearly every image texture situation possible. Personally, of course. After a couple years of building from scratch, it started to stress me out a little and now it's a much faster process. Also using a few mouse macros here and there to speed up things even more. If you have questions, I can try and help. It should all be good to go. Just adjust the normal and bump values/color ramp as needed.

It's somewhat above my level of competence, but I welcome the opportunity to learn.

Are you familiar with pbr textuers?

Just learning pbr.:)

Thanks, glad to help fellow blender artists. More coming soon.
