Hello,
I often have to do raw, unfinished wood exteriors. I find with an IOR of 1.52, even with a low reflection glossiness and bump, I get a bit of a plastic look. I remember hearing that unfinished wood is a 'lambertion' and didn't have reflectivity in the same way. Would it be physically correct to set the IOR to 1.0? Or is that crazy talk?
Thanks,
Daniel
