I'm working on a series of projects where I'm rendering very shallow water and I keep coming up against ugly marks where the water meets the terrain. (see attached images)
I've rendered the images at high detail and high AA and although reduced the issue is still present. Also I don't think its going to be practical to render at that high a setting for several minites of animation.
There's nothing out of the ordinary in the scene and its easily reproducible but I've included the file for completeness. I've also noticed that the error is considerably worse when using height maps.
So any ideas whats causing it and any ideas of a solution?
Thanks
Richard
