I think so - did it work?

That explains everything!


Wow I have been fighting against perfly (partially) and didn't even know it.


So if I just make a call to 
   pfdBldrMode(PFDGBLDR_AUTO_ORIENT, PFDGBLDR_ORIENT_PRESERVE);
                  or
   pfdBldrMode(PFDGBLDR_AUTO_ORIENT, PFDGBLDR_ORIENT_NORMALS);
(or use perfly -O 13,x) this should affect the pfdGeoBuilder state
appropriately before I load my model with pfdLoadFile, right?

That explains everything!


Wow I have been fighting against perfly (partially) and didn't even know it.


So if I just make a call to 
   pfdBldrMode(PFDGBLDR_AUTO_ORIENT, PFDGBLDR_ORIENT_PRESERVE);
                  or
   pfdBldrMode(PFDGBLDR_AUTO_ORIENT, PFDGBLDR_ORIENT_NORMALS);
(or use perfly -O 13,x) this should affect the pfdGeoBuilder state
appropriately before I load my model with pfdLoadFile, right?
