3D bug

Hi people,
When I use D24X8 dephbuffer format in a 3D patch, I have stange artifacts like this. Tried different things but it seems that nothing can fix it.

Any idea?

Cheers,
Alecz

you don’t have objects sharing the exact same place?
looks similar.

Hi kalle and thanx for replying. That’s strange but it appears even on separated objects.
