So, I’ve set up a scene with actual starmap and moon maps, and have designed a solar sail based on this image - https://www.nasa.gov/connect/chat/nanosail_chat2.html.
I’m having some difficulty in getting the moon to reflect off the front of the sail. Its easy if I don’t try to include any serious texturing, as given by the first image. But when I include a wave texture to make the sail look less “cardboard-y” (second image) then my normals screw up reflecting the sail or any other light. If I tried to mess with the mesh instead, then I’d end up with a very high vertex count, just to avoid pixelating the large, flat sail.
Any advice on the above, or any other thoughts on how to improve the image are welcome. This will be part of an animation for YouTube.
