Instant light cutoff in a hallway (screens)

[Khaz]

Need a little help with this;

Can anyone tell me how to make the light "flow" more gently down the hallway?

Images are 1024x768.

I've got a similar problem and skimming through the log for vvis I saw WARNINGS for cluster portals (can't remember the exact error).

But the way to solve it I believe is to help vis by addding HINT brushes.
