lights under water Tweet

Please tell me how in the octane plugin I can make the light like underwater?


here is an example images from Poser lights under water

is it possible to make animated reflection from the water surface?

Thanks very much for your help

The ripples would need to be some sort of morph on a hi-res plane, and would need to be animated if you want those reflections to move.

I couldn't do reflections off of water at the bottom of the sea.
morph waves does not create a refraction of light from water.
this is not the way to solve

please try to do it
then you will be able to find a solution to the problem
I believe in you! )

Even static light on the bottom of the sea would be very much needed!
I have not found a way how to do it with Octane

Poser creates this effect by adjusting the parameters of the texture in the Light settings.
How to apply this method in the Octane?

I'm sorry - I don't have time to look into this at the moment - I suggest asking in the Octane General forum. I don't find the Poser render to be particular realistic though - so I would recommend using a real underwater photo as your reference.

This was most likely done by using a light gel (that contains the caustic pattern of the waves refracting the light of the sun) on a spotlight, which was then hidden in the scene.
Doing this in Octane is possible, but requires s very specific setup.

1.) As Paul mentioned, you need a very high-res ocean plane (normal and/or displaced surface would be preferable)
2.) Set your Caustic blur setting to 0.0
3.) Use the Daylight environment, to get a light strong enough to cause these caustics.
4.) Try rendering and re-rendering, it will be tricky to achieve, but it is definitely possible.

Another (fake) way, to get this done would be to use a plane with a caustic map placed in the distribution channel of the light. Should roughly give you the same effect.

Hope this helps.

Hi we have a flooded kitchen scene. Anyway to have caustic plane to emit light pattern on the kitchen floor but plane to be invisible ? Thank you.
