Is there a way to create a camera facing normal pass for use with software such as Normality in After Effects? I'm currently using vray to generate these but is there a way to do this in Octane? Or possibly a way to convert Octane's current normal pass (which seems to be world or object space and not relative to the camera) to something that can be used with Normality? If not is there some other way of using the Octane normal passes to add rim light effects in post / what do people use these passes for? Many thanks!
In Octane you can generate three types of normals: vertex, shading and tangent.

While the two first are in world-space coordinates, the third one is in tangent space (relative to the shading normal).
Unfortunately there's currently no built-in functionality to generate tangent normals relative to the camera direction.
