we have houses in a landscape (I have an IG per house, and the landscape is
the root IG) and see their interior through a portal system (i.e. not to see
all objects but some of them?) ?

Yes you can, it works.

house?

Yes I added recently this feature (before it was all or none of the
landscape), but the landscape does not clip well against the portal (for
clip performance reasons), but it is somewhat better. Also if you look 2
portals that lead to the landscape (eg 2 windows of your house) that lie in
the view frustum, then the whole landscape will be displayed (to not clip
twice...)
