Render subsets disable GI previews

Hello guys!
anny idea why dis message pops out in vray?
I couldn’t find anything about this error online. It happens only in one scene randomly and I have to reset the render settings to make it go away.

vray next update 1.2 - max 2019

Hello,

You have the Render Mask turned on (Chaos Docs).

Best regards,
Yavor

The corrected one would be V-Ray for 3ds Max
