I heard that the amount of polygons you could add to your custom ship was infinite and depended on hardware. Well I have an X800XT and for some reason after about 40 or so pieces sections start dissapearing. Not while in the editor mind you, I'll spend an hour or so on a ship, only to find that when I finish and save, bits and pieces are missing. Also, sometimes my 'log' or whatever that little bar is that tracks your pieces screws up, and parts I delete are still in the log.
Anyway, wondering if anyone else has this prob, im sure I can add more pieces than what im getting based on the screens of other peoples custom ships i've seen. I swear its about 30 or 40 pieces in (maybe not even that) when this problem starts occuring.
