Title: Object close to a light source and noise
Post by: ECBworks on 2020-12-30, 19:59:32

I'm making renders for light and I just wanted to know if there was a simpler solution to what I do.

I used 3 light sources for this spotlight.

1- a light material behind the glass lens that lights up all that is behind the lens, including the lens.
2- a corona light circle just before the lens to light up the lens holder only
3- the corona light with an ies file and that occludes the lights just under the spotlight module.

For some reason I get some noise in the scene from light sources that are exclusive the objects
I was thinking to put a corona compositing tag to the lens holder to remove reflections, you think it could help reduce the noise?

:) Call me blind, but where's noise?!

I imagine it could be real and there would be couple or more reasons for it, but w/o looking into details I'd be just guessing, shooting blanks... How about simply sharing a test scene?

Or better, first go through Corona's Helpdesk...
