I made this as a quick reference PBR material values chart and found it very useful when making textures from scratch or quick editing NDO/Substance Painter texture values in Photoshop without needing to load the software. It is not a massive collection but it does contain a lot of the common materials encountered. The metals are shown in a dull and polished state. The non-metals all use a blue Albedo for chart consistency only, there is no set color for those material Albedo values.
Here’s hoping someone else finds a use for it!
Materials for the PBR material values chart were rendered in Marmoset Toolbag 3.0
