Rhino 8 Metallic PBR Issues

Hi all.

I’m trying to use pbr materials from ambientcg in Rhino 8 but the metallic ones won’t render correctly. I’ve tried a few different materials including this one: Metal 009 on ambientCG
If I drag and drop the zip into Rhino 7 I get the result I want but Rhino 8 renders it as a very dark metal with bumps. Any ideas on how to fix it?


Hi Claudio - I get this in both V7 and V8 on a 1000 mm radius sphere:

is that what you expect?


Thank you Pascal. That’s what I get in Rhino 7, but Rhino 8 gives me a much darker version of that.
