Show me an example. Render with a flat white so I can see the material, as well as a copy the way you're trying to do it, and I'll see what I can come up with. Notes that may help in advance: If you're doing a water surface, remember that you're gonna be reflecting the sky and all that's above it. Thus, for instance, a puddle in a coniferous forest might do well with a detained skyscape with very low silhouettes of pines at the bottom edge, for instance. If you're doing the inside of a bathtub, a simplified tile wall and ceiling might be best. A reflection map is basically mapped to a sphere and then projected downwards onto the surface to reflect. Water, like glass, would 'Multiply through lights' else you could enmd up with quicksilver. Also the reflection strength will probably not go above 50 and the hghlight strenght would be <90, probably around 50=60 A bump map will warp the reflection just like an actual change in the surface. Uhm, let me amend that -- if you use P4 on a PC and you don't make the bumpmap by hand or invert the green channel on it, it will look weird but will probably be okay on a water surface anyway.
