[Max] General Discussion / Re: Ior vs reflection colour

Thanks a lot to you both for your knowledge. Alas I am a C4D user and as such dont have access to the Siger shaders which is frustrating as I would buy them all without hesitation. Some real beauties in there. Thanks also for the link to the PBR pdf, I will sign up for that.
I have looked into IOR lists in the past and just done it again now and to me they dont line up as Id expect. Perhaps because they might take the metal in its raw rough state? For example you will struggle to see a material over IOR 3 and most in the 1.5 - 2 range. So its a bit of a finger in the air job I find. But the beauty of corona is its simplicity and its fun and quick to tweak so I dont mind a bit of tinkering to get the desired look.
Good to know that metals will always have a diffuse colour of 0 and everything is done in the reflection channel, makes it easier to focus on just one set of settings.
