I've been trying everything however I haven't been able to bake the AO pass on this one model however maya keeps saying
MEM 0.3 info : please try lower -memory settings.
MEM 0.3 info : allocation of 524000 bytes failed: flushing
mental ray: out of memory
The normals get baked out just fine though, I have never really had this problem before and it just seems exclusive to this 8k tri model.
I've even tried lowering the settings by entering
select miDefaultOptions
but that didn't help either.
EDIT:
NVM I figured it out
