Hey everyone!

Ive been trying to render a scene in Sketchup 8.0 using Vray (version 1.5 I think) that has a large water surface. Besides slowing down the render time significantly because of the reflections, I also get all sorts of weird lines and dark areas in the surface (check the attached image to see what I mean).

The water surface is a single surface that is grouped. I tried creating a basic rectangle that cuts through the model at the same height, but I got weird spots near the edges where it meets the 'solid' model.

Anyone ever had the same problem? Ive tried searching the net but couldnt find this issue yet. Any help will be much appreciated!
