Hi. Thanks for the reply. I have a very large mesh the size of a stretch of river. Which I migrated to the waterplanes level. There I added the translucent material to it and it was fine except it clipped when the camera got too close. Where as the water already in the waterplanes level is fine. I tried migrating the mesh the water is on in the waterplanes demo level to my project, but it doesn;'t seem to be a mesh and it was completely clear. Perhaps it’s a clipping problem. I currently use Waterplanes lake water as my river with no probs at all.
