Under water Lighting & rendering

[Harish_Kumar]

Hi, I am trying to create lighting for a School of fish that looks realistic.I never did under water lighting before. What lights should be used and the list of aov passes should I provide to the compositor to make it more realistic.

I Know I have to use Volumetric lights & Lights with gobos but any further details can be helpful

hi,

rather than using volume lights I find it more efficient/user friendly to fill a scene with volume fog and render that as a separate pass. otherwise there is nothing much different from lighting point of view. it's mainly the fog and caustic projection that makes it look underwater.

Thank you very much I will try it

But I have to get fog from an fx artist is there any way to render without using fog

you can use zdepth in compositing to create sort of fog effect but you won't get light rays that way.

creating volume box is really easy thou, you don't need an fx artist for that. just drop a box in your scene, turn it to volume and render with uniform volume material.
