Hello,

I would like to load a Flight file and render it sorted in BINs.
I have made a small addition to complex.C to draw individual bins.

The code in the drawcallback is someting like

if (Shared->keyBin == 'a') pfDraw();
if (Shared->keyBin == 'o') pfDrawBin(PFSORT_OPAQUE_BIN);
if (Shared->keyBin == 't') pfDrawBin(PFSORT_TRANSP_BIN);
if (Shared->keyBin == 'm') pfDrawBin(-1);

All the pfGeoSet::getDrawBin() return -1.
This way pfCull should put the geosets in the right bin.

For key 'a' I see all the polygons.
For key 't' I see only the polygons that are transparent
For key 'o' I see NOTHING
For key 'm' I see only the opaque polygons.

If I explicitly set the bins to OPAQUE and TRANSP bin
nothing changes. Still no polygons in the OPAQUE bin.

The CULL mode of the channel is set to PFCULL_ALL (includes PFCULL_SORT).
 chan->setTravMode(PFTRAV_CULL, PFCULL_ALL);

I use Performer 2.2 on an Octane and O2.

What could be the cause of this strange behaviour?
