This scene is only about forty feet deep, but the surface is partly cloudy : ). I turned down the ambient light - something I've never tried, thanks Mark. I like it better now. I'm having issues with the texture map stretching at the top, creating longer scales at the ridge of the back - same old issue as many of you experience. I need to learn how to split the mesh in Hex and approach it that way. Thanks for all your help.

Never Give Up!
