Max number of polys per model? [SOLVED]

[Giftheck]

I seem to have hit a snag with my redo of the Carbon Freezing Chamber. The map currently crashes when I attempt to load, so it got me wondering if there is a limit to how many polys each child object can have, or whether there is an 'overall' limit for each .msh. If there is for the latter I will need to split it into two objects.

EDIT: I believe this to not be a mesh limit I've hit but a materials limit. I created a version of the new mesh in the old Carbon Freezing Chamber using a single material so I can see what I'm doing in ZE and it works just fine. The original model till munges and works ingame.
