Linking messed up Material

So I grouped my rig and linked it to another file, and made a proxy of the armature. Everything seems to be working fine except when I render it the eyes turn out black.

The eyes render as intended in the library file So I don’t know what to do.

The eyes are made with two spheres, a smaller one inside of a larger one. They are joined together to form one mesh.

The inner sphere uses a radial blend to make the colors, there is a cloud texture on it to give the iris a little more color, and a radial blend stencil to keep the cloud on the iris.

The outer sphere is completely transparent and just gives the eye it’s shine.

Anyone know what the problem is?

Thank you.
