ok done all that and it is looking good know I have generated caustic with a bitmap image this way it cuts the render time down as well
I am know trying to animate the scene and I have successfully animated the light rays but I don’t know how to animate the bitmap caustic I tried changing the phase but nothing

Lookup the tutorials in 3dsmax. I seem to remember that there was fluid dynamics. If not there might be plugins that can do what you want.
Also, if you know the scale of size your props will be increasing and their rpms it would be easy to model/animate.

If haven't done this for awhile, but you can probably use a volume light with a projection map. (That might go by the name of shadow map... and have it project something similar to caustics.)
Post some renders, use imageshack.us if you can't upload them on here and then paste the forum url it gives you.
Also you can use Photoshop like this: render without rays, then as a overlay have your rays shopped in.

Thanx for the reply Lantzvillian
Concocting will not realy work and I don't know enough about scripting.
Do you know of a program that I can use?
The idea is to design a full scale windtunnel on computer before building it. It will be much more cost effective (and time effective) if I can do a design on computer than to build, and rebuild scale models.
Tanx again.

It should work with a single light in your scene. The texture your sending it through or at.. can it generate caustics. If I remember correctly there is a setting that has that.

I am using mental ray renderer for the caustic and applying it to a surface with a displacement map on it but I can only seem to put one light in the scene
I don’t know that much about rendering with mental ray

What renderer are you using? Volume lighting will help create the rays. However, most implementations of what you want to do I have seen mostly done with Photoshop.
For caustics, are you bouncing the light through a rippled surface for example?
