Quote - That's why I was asking about memory, if the crashes depend on the number of objects loaded and not on which object is loaded, then you might be running out of memory.

The problem isn't tied to the number of objects in the scene, just to specific objects.  I could load any of these scenes into Carrara or render in P7 with no trouble.  Turning objects on one at a time was just the method to find which ones were the problem.  Even exporting out just the one object caused a crash in Lux.
