The answer here must come from the guys who made O2.
The events that cause model not to show in bulldozer seem to be either. 1, too many faces
cant be because i have 2 models and the 1 with the lower face count wont show.
2, too many components
again...cant be that because the model with the lower component list wont show.
I gave the texture memory in O2 1ghz to play with and no difference occured.
Patch or reason from the O2 Dev's would be great
