Hydrax and caelum problem


11-11-2008 03:05:38

I add hydrax and caelum in my project and everything looks normal except caelum's star.
At the beginning ,the camera above sea level, I can see the stars of the sky. When the camera moved to below sea level, i can also see the stars. But when the cameras once again moved to above sea level, i can not see the stars. At this time i can only see the stars below sea level.

Can you suggest me something?
