the polygons are optimized into tristrips and more likely flat tristrips.

this mode shouldn't matter if you have normals.

note that you must set the face lighting mode in multigen to "Dynamic" or
"Dynamic Gouraud". the openflight loader only considers normals under these two
settings.

instead call:

    pfdMesherMode( PFDMESH_LOCAL_LIGHTING, PF_ON );
