Usually I can hide or extend the wall although since there is a mirror against the back wall, i would like to retain the wall in the reflection.
I have tried,
-Messing with the Near Clip Plane = Renders Black
-Unticking Double-Sided in Maya’s Render Stats whilst also deleting the back-faces = Renders Black
-Unticking Double-Sided in the VRay Material Options whilst also deleting the back-faces = Renders the wall with a translucent effect.
Thanks for that. Whilst I was trying to find the visible to camera option, I found that disabling Primary Visibility in Render Stats was the solution I was after. I must have missed that function in the beginning.
