Lights, opacity and refraction exclusion
Posted: Mon Feb 29, 2016 5:42 pm
Hi,
Suppose I have a simple scene: https://dl.dropboxusercontent.com/s/ava ... ity_01.jpg
I want to hide lights from being directly visible in refraction, checking "camera visibility" for clearer indication of what's going on: https://dl.dropboxusercontent.com/s/zd5 ... ity_02.jpg
Then I turn down opacity to 0 and get this: https://dl.dropboxusercontent.com/s/pe4 ... ity_03.jpg
Yes, lights are not directly visible in refraction, however picture looks completely different. I checked multi-pass and it turns out all the channels remain intact, except for Indirect Reflections, they disappear almost completely.
Refl I. Channel - opacity 1: https://dl.dropboxusercontent.com/s/b2a ... ity_04.jpg
Refl I. Channel - opacity 0: https://dl.dropboxusercontent.com/s/kf0 ... ity_05.jpg
Is that a bug or a feature? That's pretty sad considering some scenes would be impossible to light in a straightforward manner without compositing and rendering in multiple layers where it'd be unnecessary.
Thanks!
