PBR values for alloys

Author Topic: PBR values for alloys  (Read 978 times)

Hello,

I'm getting a little confused with following PBR standards for metals.
Generally I use a black metallic map for dielectrics and white for metals, including alloys and other metallic materials. I would only use greyscale values for rusted/oxidized metals.
If I make a make a bronze material and I give it a dark reflection color, the PBR validate filter marks it as incorrect, because the color should be much lighter, or I need to lower the metallic value changing it to light grey. Does that mean that only for pure metals a completely white metallic map should be used? and for alloys and similar materials it should be a greyscale metallic map?
