Underwater Caustic Effects
I am trying to learn how to set up under water scenes. I followed a tutorial on Youtube for one which came out ok but not particularly noticeable in the scene. I found the "water reflection" gel in the special bryce folder so that was a plus. I tried another tut for underwater rays, ok but sparse and unconvincing. I have a couple of questions:
1. How can I make my own water reflections gels
2. Where can I find some?
3. Using the term "caustics" doesnt bring up much in a search, is there another term to use?
4. The underwater rays -how does the sky lab affect these? I am using a sky as the underwater colour. Sometimes the volume light rays show but usually they do not. The sky is cloudless with a high haze as suggested.
I'm going for a somewhat tropical sea. Not too murky but not crystal clear either.
I'm not very knowledgeable about the light lab, I've learned what a few of the buttons and sliders do, but I'd like to get on with my scene. I didnt use volumetric slab because I don't want to render for hours.
Any suggestions will be greatly appreciated
