Hello,
I'm trying to set my lights for an interior rendering but I'm getting a problem with strange illuminated area above window (picture). I've been searching for the source of this but I have no idea what may be causing it. I was thinking about it being reflection from below surfaces, but the problem lasts even with an empty room. It's not being affected by Vray sky environmental map eighter.
I was trying to play with exposure values, they seem to affect it a little bit, but still it's not ideal.
I'm using just Vray Sun with default settings, no other lights, GI on Brute force and Light cache.
Any ideas about that please?
