I have a post processing Material applied to my cineCamera Actor that depends on the mesh of the nDispay and uses the worldPosition node. After switching the nDisplay material asset to opaque It works in the editor, but when I render the nDisplay node with switchboard the mesh becomes invisible to the camera and I only see the world position of the scene behind the mesh (which is normal but in my case I want to change it)
I could not find any documentation regarding how nDisplay is rendered.
The only solution I have in mind is to use a second camera duplicate that only sees the mesh and somehow feed its view to the post process material of the other camera. But that seems kinda ugly.
