VRAY LIGHTS IN AN EXTERIOR VIEW?

[gitano_anton]

Can be useful to put Vray lights in the windows to illuminate the interior of the house and that can be viewable from the exterior?

perhaps...

try turning shadow casting off for your glass objects and exclude them from GI completely then up you GI emit values [something like 1.2, 1.3] for balconies, awnings, floorplates etc...if this doesnt give you more light inside to your satisfaction try the vray lights...
