I am using a texture as Environment Background in the Vray Environment Node. I change the settings so its not visible in the reflection. Local rendering works fine. After saving the frame to a vrayscene and render it in the farm the reflection is back.
Scene File that shows the issue is attached.
I’ve reproduced the problem and logged it in our tracker. As a workaround, you can plug a V-Ray Color VOP into the “reflection” input of the environmentSettings node, and set the Color parameter to black.
