Limit indirect diffuse ray distance - ? ( Arnold )

Recommended Posts

Posted (edited)

Sorry to ask this here but I can't find any info on this ;


Trying to figure out if I can set a max distance for indirect diffuse bounce calculation, via nodes if there's no controls for it. I don't know the 3D math, and would love to learn it.

Rendering a city at night, and neon lights are causing lots of noise on buildings too far to show their contribution anyway. It should greatly speed up Arnold's slow renders regardless of neon too. ( and switching to mesh lights has been a buggy nightmare anyway )
