I am starting to play around with IORs and fresnel reflections - never really messed around with them before and have always used falloff maps in the reflection slots of reflective materials - glass/ceramics/metals etc.
However, I thought I'd use the table of IORs at vray.info. Lots of info in that table, but what would I use for stone - a nice, limestone, like 'freestone' or ashlar I guess.
