I once had this problem when working on missiles. Some missiles had z-coordinate 
in infinity IIRC. When I fixed this, everything was normal again. No idea what exactly 
caused it though.

Is this still happening?
Few months ago or so, I had some problems with particles. They simply weren't rendered, even though rendering counts showed that they should be rendered. But lately, it hasn't happened anymore...

I had this some weeks ago.
Transall bomb might be the reason for this

3 months without additional info and I've never faced this problem. I believe it has been fixed meanwhile, so I am closing this now. Please reopen, if it happens again.
