Hello there,
I'm relatively new to Redshift an encountered a problem that by searching and looking into the documentation I couldn't solve. I set up a simple scene with an Ocean (Standard material with slightly modified Water Preset) and a rough sand-like surface beyond the Ocean. Whith caustics enabled in the Domelight settings i get smarties, where - beyond the water surface - caustics should render. Why?
Modified Redshift ROP Settings:
Unified Sampling: 128 - 1024
Global Illumination: Primary>Brute Force, Secondary>Irrandiance Point Cloud
Photon Mapping: Caustics & GI enabled
A hint here would be much appreciated! Thanks
