Hello everyone,
I need some help because i cannot figure this out myself.
I have two volumes layered like cloud strata. It seems that Houdini’s Light Linker doesn’t fully block light as expected. When I try to restrict a light to only affect the lower cloud layer, global illumination still appears to bounce off the upper volume. For example, even with a single downward-facing light meant only for the lower clouds, the upper volume still receives some indirect light. As soon as I set the Volume Limit to a value like 32 in Karma, the upper cloud starts picking up bounced light from the lower one, which I’m trying to avoid. I had assumed the Light Linker would isolate the lighting completely, but that doesn’t seem to be the case. This is becoming quite problematic for the look development of the project, especially since our scenes are very large.
Thank you
Alex.
