Quote - Acadia,

Another (fun) word for torus is donut.

The water in the tub was actually part of that prop. I downloaded it from freestuff. Can't remember what the name is or who made it.

As usual, I deleted that water material a long time ago. See, when you make several hundred shaders a week, you just can't bother keeping them all. It takes less time to make them from scratch than to find them among thousands.

All you need to make good (clear) water is the fresnel node. Just hook it up to the Refraction_Color and set Refraction_Value to 1.

After that, you want to put some displacement on the water. I've used fractal_sum here to demonstrate.

Do I need to link you to that fresnel article again :)?

Ahhh, donut or "ring", hehe  I'm going to ask for a dozen "torus" the next time I go to Tim Horten's,  LOL

I searched for bath tubs the other day and I did see the one you used, but for some reason I couldn't find it on Gerald's site. Today I looked and there it is!!! 

I'm going to try this this evening.  I have the Fresnel node threads bookmarked. I'll post my results :)
