il faut utilisé le metaSelector :

scene::IMetaTriangleSelector* metaSelector = smgr->createMetaTriangleSelector();
metaSelector->addTriangleSelector(selectormap);
metaSelector->addTriangleSelector(selectormaison);
...

scene::ISceneNodeAnimatorCollisionResponse* choc = smgr->createCollisionResponseAnimator(metaSelector, camera, core::vector3df(45,75,45), core::vector3df(0,-15,0), core::vector3df(0,50,0));
camera->addAnimator(choc);


Si ta des questions...
