I am also dealing with intersections. In the scene, there are different types
of objects, set with different intersections masks.

Some are set from the pfGeode :

mGeode->setTravMask(PFTRAV_ISECT, 0x2,
                    PFTRAV_SELF | PFTRAV_DESCEND, PF_SET);

Some, from the pfNode created by pfdLoadFile :

pfNode* model = pfdLoadFile(fileName);
model->setTravMask(PFTRAV_ISECT, 0x1,
                   PFTRAV_SELF | PFTRAV_DESCEND, PF_SET);

The problem is when I check for intersections by :

pfSeg segSet;

segSet.mode = PFTRAV_IS_PRIM;
segSet.isectMask = CCollisionManager::OrganMask;
segSet.isectMask = 0x1;
segSet.activeMask = 0x03;
segSet.userData = NULL;
segSet.bound = NULL;
segSet.discFunc = NULL;
segSet.segs = ... my two segments

ECHO(" Nb Segs " << mRoot->isect(&segSet, mHits));

I get intersections for ALL solids, it seems to ignore intersection masks.

Has someone an idea about this behavior ?

Thanks in advance,

  Didier
