I am enjoying the geography that you have created hear. I do not know if it is realistic, but it gives off the impression of realism (which is all that matters!). Good work on that. I would really like to see the planet rendered with earthy tones other then the saturated colors that have been used for obvious reasons! I believe the key to these aerial views is a more complex oceanic system that allows for varying color. Traditionally we would just use transparency on the water shader, but we all know that is not implemented yet! I bet there is a way to add color onto the existing water shader, and if we could figure that out it would be a lot easier to make realistic oceans. Hmmm is it possible to use the water shader as a parent layer, and then add color shaders to that? Just a thought, I cannot test the theory out!
I have a question though. These aerial views seem to intrigue a lot of the forum members. Why is that?
