I cannot set objects on or behind the horizon..what am I doing wrong?

[Mako666]

I've been using Bryce 5 for a few years now, and I've never been able to get objects on/behind the horizon. The other day I managed to accidentally get a mountain set behind the horizon, when I wasn't even trying to do it. It just sort of jumped there... anyways I can't figure out how that happened, and I have never been able to find a tutorial or anything online about how to do this. I'm hoping somebody here knows how. Please please help me.

By horizon, what do you mean?
The only way to make an item as if it were outside the atmosphere would be to move it very, very far away.
Try to be clearer...
