Make a shader only visible in reflection?

[Anonymous]

Is there a way to have one shader only be visible in the reflections (of a mirror) and another be visible directly in the camera, on the same object?

I want to create a scene where one object has another shader when looking in the mirror.

Or is this something best done in comp?

ray_switch does exactly that.

Ah, of course. Is this not yet supported on GPU? I get a black shape with a standard surface piped into the Specular reflection channel in the ray_switch.

I just tested (in Maya) with Arnold GPU and a rayswitch, and it works.
