Vray - remove HDRI reflection on a mirror


#1

I have a scene where a mirror will reflect the outside of the scene, thus showing the HDRI map in the reflection. Is there a way to simply hide it for this object only? Disabling the vray dome light reflection does work, but also affect everything else making everything have flat reflections.

I’ve already tried excluding the object from the vray dome light and set to invisible, fiddled with the alpha channels and all that. I could fix it in post using the alphas but due to the extreme overexposure it adds a lot of artifacts along the mirror edge.
