Hello there, does anyone know how to reach this effects : God rays underwater.

See example.

{Edit] : it seams that volume shader god-rays does not work with caustics, as the ocean plane sends caustics, but blocks the light for volume shader.

here is the test i've made, as you can see, we have caustics from ocen's plane, but the only godray we get is from ocean's border.

Would have to do it without caustics - best way I can think of is a light projecting a caustics texture (the old way of faking caustics for such a scenario :) )

I did that also, as i bought a "caustics generator" license, back in the old days...
But i was trying to be more accurate / nice...
