Hello all.

I am doing collision detection of an aircraft with the scene, and of
course don't want the isects intersecting with the aircraft model, so I
changed the aircraft node mask to 0:

 aircraft->setTravMask(PFTRAV_ISECT, 0x0, PFTRAV_SELF, PF_SET);

The problem is that this is not working and the aircraft is detecting
collisions with itself.

I have solved the problem by adding a node callback to the aircraft:
 aircraft->setTravFuncs(PFTRAV_ISECT, preIsect, NULL) and the preIsect
function returning PFTRAV_PRUNE.

I think the right way to do this is the former one, so I would
appreciate any comments about solving the problem by setting the
aircraft mask correctly.

Thanks.
