Lightmix Rest Issue with Directional value.

[francomanko]

So I'm having issues with the 'rest' attribute of the lightmix. With cpu its fine, but with gpu i have to turn off 'rest' to match the renders. For me it seems to have something to do with the rectangle light directional attribute, but who knows.

Ive attached scene and a video can be seen here

I managed to reproduce the issue on a simple scene. I'll write back with more information.

EDIT: The issue stems from the fact that there's a mismatch between the RGB and a Full VRayLightSelect when a VRayLight has directionality active. Logged the issue (internal bug-tracker id: VGPU-6335).
EDIT2: Edited cause of issue.

thanks for info, does that mean turning it off is ok?

Yes, the images between CPU and GPU should be identical when disabling Rest.
