If object is too big iteration over all tiles covering it can take too much time. Limit bounds to a square around a player position to cover only tiles that will be present in navmesh based on max tiles number option. Each object is associated with a set of tiles its present in. Culling can reduce this set but it has to be update when bounds change position. Do this in TileCachedRecastMeshManager::setBounds updating the set and adding/removing objects to the corresponding CachedRecastMeshManagers.
