Maya Spotlights and V-Ray - barn doors have no effect.

V-Ray V-Ray for Maya Issues
1

Can’t seem to get barn doors to work with Maya spotlights - they have no effect on the light at all. I’ve rendered with both GPU and CPU. Mac OS 10.11, Maya 2018, V-Ray 3.6.

Hi,
I’ve made some tests and it seems that they don’t work when rendered with VRay GPU. They work fine with CPU and V-Ray 3.60.04. It might be in your specific scene that it doesn’t work and if possible sharing a scene where the problem is reproducible will be very helpful.
I’ll add a feature request to our developers to add support for VRay GPU in the future releases.
