Lighting square area?

[tue_nguyen]

I'm using BF+LC with Progressive.I don't know why i have this area. And it's noise more than other area too.

Do these go away if you switch to Full light evaluation or increase the value next to the Adaptive lights?
Also which V-Ray version are you using exactly?

Adaptive domelight perhaps?

Adaptive light = 8. And adaptive for Domelight too.
Vray Next.

Disable adaptive domelight. If the errors are in the GI might be from this feature.
