My nightmaps work but at the wrong time as they only appear on the day side of the planet, the night side is just black. is there any way around it?

thanks in advance

David,

I have never heard of THAT before. Please provide complete info about your OS, graphics card, Celestia version, and all the usual.

Otherwise your case is like if your friend asks you: Hey, my car stopped running. Is there any way around it?

Bye Fridger

Could it be that the night texture needs to be reversed?

In other words, might it require an orientation which is offset by 180 degrees?

Just a thought...

Thanks, Bob

David,

could you first eliminate that it isn't just because the nightmap happens to be covered by the cloudmap on the night side? Cloudmaps cover nightmaps. Nightmaps are visible even on the dayside. Also, check the nightmap doesn't happen to be rather empty on the night side at the time you looked.

Switch off the cloudmap, advance time by half the day of the planet and see if night lights appear.

I find that if a planet gets rendered incorrectly, toggling the window between full-screen and windowed fixes things (Restore, Minimize, etc).

If you do a have real problem, post a piccy of the planet as it appears in Celestia, also the night map and the cloud map.

Spiff.

I've noticed that if the planet is illuminated by X, T, L, S, N, R, C and M stars, night lights appear more bright. If the planet is illuminated by K stars, night lights appear darker. If the planet is illuminated by brighter stars like G, F, A, B, O, W, D and Q, night lights doesn't appear.

Is your planet illuminated by K or redder stars?

I forgot to mention that the planet that is not illuminated is earth and our solar system i have seen it work on other computers but not mine.

Ive took a picture of europe (as it has the most light) with no cloud maps and half lit and half dark and it is not visible on the night side i would post it but i have no suitable web space to link it form

Thanks david
