I made some water animations in 3DS and with RayMan.
If the water doesn`t flow and you have to look through the water:
make a plane with GRID, apply a (animated) bump map. Make the
material very transparent, give it a (extreme) little touch of blue
and make it a little bit reflective. Under the water plane place an
other plane with a ground mapping (ocean ground or a ground of a
swimming pool or whatever you want). You should make the ground
mapping with a warping program like Elastic Reality. Than render a
sequence of distorted images and use them as an animated ground
mapping. Then you should use a projector light with the caustic flic
to illuminate your ground mapping.
This works fine for a lot of jobs. If you want really perfect water you need
realistic refractions and multi reflections. You need a raytracer like RayMan
(<g>)!
You should buy RayMan (the 3D Studio raytracer). If you have it make the
following additional to the things described above: give the water material a
nice reflection map (for e.g. a sky). Then load the material into the RayMan
material editor and set the REFLECTION MAP RATIO to 0.5. That means that RayMan
reflects 50% of the reflection map and 50% of the 3D scene. Set the INDEX OF
REFRACTION to 1.333 (or higher).
Hope this gaves you some little tips…
