| Underwater Scene |
 owtdor |
I have been running through a ton of tutorials on underwater scenes this morning and nothing really is giving me a great result. Anyone have any other sources I might not have seen yet?
I need to create an animation of an anchor "setting" itself in a sandy ocean bottom. It needs to be lit enough to show all the detail, but not so bright that it looks like it just a few feet from the surface. There does not need to be any caustics since it will bog down the render times and might throw off the views. (You never know if you are going to get an epileptic juror that goes into fits when you show caustics)

There are no caustics anyway past a few meters. It's all scattered and averaged away.

I have had some success with using a gradient (black to blue-green) in the environment map for the background. Crude and predictable.

lots of "dust", volumetric lighting, lights coming from the camera and volumetric fog.

Going to try building this again today. Any other suggestions?

I read a tutorial where the guy created a plane above the water and cut loads of random holes in it then projected a single light from above. Gave a really nice lighting effect. Something I've been meaning to try.

It`s amazing the things that are done so simply and so effectively within real time games that are a whole lot of arsing about with 3d apps..

I have a book that is pretty old, but it has a tutorial on an underwater scene. It covers everything from creating the materials to doing the caustics for the water, creating plankton and bubbles. It is about 100 pages long, but i would be willing to scan it and email you a copy if you want.
it comes out pretty decent.

Got it pretty well sorted, thanks for the post everyone.
I do have one more question though, is the "Fog" environment effect not compatible with Mental Ray? If not, how do you suggest I get a fog into Mental Ray?

It is indeed not compatible!
I think the "Parti Volume" shader is the one you want.

I recently did some underwater work. Depends on your pipeline i guess, i used vray.
in environment effects i had VRayEnvironmentFog, you'll have to play a bit with the settings in there to get the look you;re after, in vrayenviornmentfog nodes, under lights, i had two lights, one of them a vray ambient which was pretty lower power and a dark blue, and i have a direct light over head casting an animated water caustics map downwards into the fog, giving pretty good light streaks.
might need a second direct light to cast shadows, all rendered without GI, but with the fog it will be pretty slow.

I don't currently have access to Vray, and even if I did, I have never used it. I love the results I have seen though.

I got it figured out by following this tutorial and adjusting it to my needs.
http://www.polygonblog.com/3d-underwater-scene/
I also found out that the lighting I originally put in the scene was messing things up.The first try was to implement the tutorial into my existing animation, but I ended up building the tutorial file and then imported my scene into it, minus the lighting. When the trial is over I will post up some renders.
