There is a patch for RexDotMeshLoader multiple submesh loading at http://forge.opensimulator.org/gf/project/modrex/tracker/?action=TrackerItemEdit&tracker_item_id=402
This should (at least theoretically) help the multiple submesh collision issue. As far as I know, it has not yet been applied to trunk. - Lasse / realXtend developer -- http://groups.google.com/group/realxtend http://www.realxtend.org
