I am working on water and sky for my USS Niagara WIP. THe problem I am
running into is the spots in the sky. The biggest and most visible is at the
far right. I thought it was a radiosity problem at first, but after working
radiosity for a while, I don't think it is anymore. Anybody have an Idea?

Here is the SDL.
