If you are search that from where is my clipboard in windows 10 then i have seen that from the google i have collect all the information because it is the right place that you know very clearly.
3D Artist Lee Devonald released his channel display shader for Marmoset Toolbag 3 on Gumroad for free.
This shader is said to mimic the Marmoset Viewer channel display feature, allowing you to post detailed breakdowns of your materials in high resolution.
One note i would make:
Local Reflections will show up as they are a screenspace effect, so if you’re getting an almost fresnel like effect, make sure to disable that.
Currently using Skin or Microfibre diffuse settings will cause some “bleed” into gloss/reflectivity. I’m working on removing that, but it won’t be easy as i don’t have access to certain things.
Make sure to check out the artist’s works here.
