Conditional Shader Question

Is there is a way to assign two materials to the same object but have one of them the primary material and the other only viewable in reflections while the primary is not visible in reflections?

Thanks!

You can use a rayswitch shader (mental ray) or an equivalent one.
In mental ray they are part of the production shader

so you have to unlock them, or you can mel

 shadingNode -asUtility mip_rayswitch

Another question about this rayswitch shader. Does it work with layered shaders? I have two layered shaders that both have a metallic mia material and a blinn material applied. The layered shaders both work when applied individually but when I plug one layered shader into the reflection and the other layered shader into the eye of the rayswitch only the eye shader shows up.

I've set up plane with the builtin_bsdf_mirror material applied to it to test the reflections but again, the reflection of the rayswitch doesn't render. However everything else in the scene I want to display shows up in the reflections.

Any idea as to why this doesn't work?

Thanks for your help!

Edit: Nevermind, as soon I posted this I realized the Visible in Reflections/Refractions was off in the Display properties when I imported my new mesh.
