it’s a very old wish and maybe it’s possible to get it working for the new release - could it be possible to enable refraction transparency for the material id channel? Often I render watch designs and I like to fine adjust parts in post work, but the current material id doesn’t show the material id behind the glass.
Hello, Micha,
What you described is not possible.
To achieve the requested result, a second render (quick one, lower quality) needs to be done and the obstructing object/layer either hidden or cut (VRayClipper).
