Comment(by jorrit):

 Having only one sector per movable isn't really possible. Let's take a
 case where the origin of a mesh is in sector A but the mesh is big enough
 to traverse a portal to sector B. In the solution of only one sector per
 movable the mesh would be registered in sector A and have a list of
 portals containing the portal to sector B. That's fine when you are
 rendering sector B through the portal. However, if you are in sector B and
 the portal from A to B is not visible you have no way of knowing that you
 should actually render that mesh.

 I don't understand the third solution?
