HI Petr, The ray intersection testing goes right down to the polygon level when testing for intersection so "expanding" the bounding box won't make any difference.
Perhaps what you are looking for is the PolytopeIntersector, this allows you to create a screen aligned polytope that can intersection objects within the polytope. Robert.
