John,

you seem to be intersecting with the vehicle graph although
it's not entirely clear.

HitNum = ModelsParentDCSNode->isect(&Isegset, Result);

If ModelsParentDCSNode is the vehicle DCS then this is wrong.
You need to transform the vectors *positions* through the matrix of
the vehicle DCS and intersect with the scene terrain node. Be sure
and include any matrices you may have above the terrain.

Use pfVec3::xformPt for this position transformation.

Cheers,
Angus
