... as opposed to using physical sky or skydome for interior renders - Has anyone tried it, i know that it may be considered a bit of a cheat but if it gives good results and renders quicker (direct light) then it may be worth it

Only problem would be that a sun emitter would not be able to penetrate the emitters in the windows

What do you think?

yeah "sky portals" is a very old and very good idea

Dunno about sky portals, never used Vray. I have tried single plane emitters in widows though, but I found the physical sky or skydome to be about 10% quicker to the same sample level. Although the scene I tried it in also had additional emitters for light fixtures in every case.

no need to go vray way, lightscape was using it long time ago
