Now, onto a couple problems I'm too much of a newbie to figure out.
1. When adding a bumpmapped texture to Earth, the planet loses its reflectivity with the sun... even if I add a transparency to the bumpmap.
2. I find that the Earth's nightlights texture is visible way too soon. Is there a variable in the code that could fix this?
3. More of a suggestion than anything. Comets in Celestia are indistinguishable from asteroids. Maybe in an update or add-on, comets in celestia could be given actual tails, perhaps by using volumetric fog or sprites. It would be a nice new eye-catcher
