Interior scene modeling

[frank1331]

If I am creating an interior scene, how much of the building do I really need to create in order for Vray to give me a fairly accurate output. Obviously I need to create the room itself, but how much of the adjoining rooms and windows would I need to model?

You basically want all walls completely closed so you don't have any light leak issues. I guess it all depends on the amount of light and what the camera is going to see. If you have reflective objects, you need them to reflect something and that is were modelling objects that are not seen the camera come into play.
