I have had a surprisingly difficult time getting caustics to work for a swimming pool.
I'm using:
- basic Water material provided by V-Ray with the material Fog Multiplier reduced to 0.01. It is applied to a plane. I tried a volume, too.
- GI Caustics Reflective and Refractive Caustics are checked.
- Photon Mapped Caustics is enabled w/ defaults.
- Sunlight is only light in scene with Caustic Photons Caustic Subdivisions increased to 6000 and Emit Radius increased to 500.
I added the Caustics Render Element to see if anything was happening. It is black.
I've changed the Photon Mapped Caustics settings way up and way down.
I've changed the Sunlight Caustic Photons settings way up and way down.
I'd be happy to upload images/screenshots/files if somebody is willing to help.
