This probably sounds really odd but I'm trying to make the water, terrain, and sky all BLACK. Nothing else, just black. I would want to keep the directional sunlight though so that the aircraft would be lit when using an external view. Not much good for flying I know but it's related to large amounts of aircraft screen shots and the need to automatically remove any background.
Thought someone here might know a bit about messing with standard FSX textures etc.
Look forward to any replies,
