First time converted no prob. Second time I reduced size by a 10th to get close to accurate for fighter size (albiet a large one). Added 2 turrets and a shield. It converted but I forgot to add a light to shield.
Went back added light, saved. Conversion fails BSP recursions.
Went back removed shield - crashed..
Removed turrets - crashed..
Went back to original size - crashed
Can someone look at the model and tell me if there is a geometry error? (if so thanks!)

[Edit] Modelview converted the shieldless one though I forgot to make the turrets invidible. It's still too big by 50%
