I’ll send you the scene when I finish work later this evening
The water has regular settings, a bit of noise for the small wavy effect and IOR is standard water (1.333)
I’ve been modifying the scene somewhat but I’ll send you a simple version of my setup for you to explore
You’re using Vray I believe, which version of Max do you have?

You can use this scene which came straight from Vlado @ Chaosgroup, I take no credit for it
All I have done to differentiate my scene from the one in the link is remove the fog and the bubble which surrounds the camera, I originally thought the bubble was needed to return the correct effect (Snells window) but it seems that the bubble is only required to ensure the correct refraction fog colour is returned
One negative effect of wrapping the camera in a bubble is that technically you are rendering through something (in this case water) and so the only useable element would be refraction, this is obviously quite a bad thing as you in effect get no elements and may as well just colour correct the RGB. Removing the bubble allows you to render a normal image and have all of your elements available to composite with (much better!)
