Here are some new completely procedural (path tracer-!!) metal materials made entirely from scratch.
By the way, the ground shader is a mix of two merged PBR materials, one from cgbookcase.com, and the other one from Quixel.
I used a transform input shader with "use world space" checked before each PF to override any existing UV mapping of objects. Otherwise it may look a bit weird.
This is great. Thanks Hannes!
They look very good. Very handy. Thanks very much, Hannes!
These will be very useful. Thank you, Hannes!
Awesome stuff, though maybe the gold needs higher spread. Gold is pretty bright under sunlight. I haven't seen a gold bar under sunlight by gold panning, those fleks and nuggets light up like yellow under the sunlight cause the reflective spread seem high.
