this is the pof generated by pcs1.33 seen in modelview
this is the pof generated by pcs 1.101
this is the hyerachy of the model (i tested dozens of combinations btw and i noticed it change a lot, but i wasn't able to find a solution)

the "missing" subobjects are present in the subobject list of pcs, it is like if modelview find 6 lods instead of 4, and althought it doesn't show debris details they appear if i click on them (the missing lod instead can't be seen)
i also tryed to convert the right pof->cob with pcs 133 and reconvert to pof, but the result was even more odd
i think i'm probably doing something wrong with debris but i can't figure out what, btw it remains strange that i have two outcomes from the same model using different version of pcs
i haven't tested the model in game
any help is welcome
