There seems to be a bug when using the render setup and AOV with V-Ray render elements. Here is a “manual” workaround to be able to enable/disable V-Ray render elements.

  • RMB click on the render layer that you wish to enable/disable render elements for and create two collections. To make it obvious what it does I called the collections render_element_on and render_element_off

  • open up the V-Ray render settings, go to the render elements tab and select the render element from the added render elements list

  • select the appropriate collection in the render setup and click add

  • change the collection filters to All

  • in the attribute editor of the render element MMB drag the Enabled checkbox to the “Add Override drop area” of the rener setup widget

  • add as many render elements to the on / off collection as you need
