Eclipse shadows not working for Jupiter small moons?

[andyrock]

Hi!

Jupiter eclipses Io, and I can see it dark without problems, but when the eclipsed body is a small moon like Thebe

or Amalthea

, I get no eclipse shadow. I don't remember this to be broken - I'm using latest CVS under linux

[EDITED]

I believe that the same goes for spacecrafts:

Eclipses only work for Celestia's builtin spherical objects.

They do not work for objects which are defined with the Mesh command.

Maybe in some future version of Celestia...

Further explination...

Eclipses in celestia aren't based on a realistic lighting model (as in Doom 3). Ratehr they are faked in a similar manner to the circular shadows you'd see beneath things in older video games.
