Opacity
Does "Opacity" slider on materials have any physical meaning? I have glossy translucent material with ior e.g. 1.5, world volume ior 1. I make glossy translucent 0.2 opaque, and it does look otherwordly.

Re: Opacity
I don't think so.
It is mostly intended for masking out parts of a mesh, for example leaves or grass (so you can model them lowpoly and create the shape with an opacity mask). In the past, people where mixing with the "null" material to achieve this, but that was rather slow, so the opacity value was introduced as a fast, optimized path for this purpose.
