The problem is, NOTHING in 3D is natural so, depending on the shader settings, anything can look wacky. I don't have a preset in my browser "new water" so I can't take a look. The C5 water shaders that I do have are working as expected though. Just double check a couple of things: Is the water transparent? If so, what color the object or atmosphere beneath it? Is there a background image that is showing through? Nothing but questions... ;)
