I always kind of wondered, if this effect was simulated in-render by any renderer. Wasn't really able to search out anything on it.
Some of the effects of polarizing filter in photography can be of course achieved, atleast on surface visually, in post-production, but not all of it,
is it affects reflections quite a lot.
Seems there is very little interest on it, not sure what I am missing. Seems to be imho great contributor in pleasing photorealism.
