Oh and thanks for the awesome tool that Shader Forge is :)

Hi,
I'm having the same issue with deferred lighting and trying to use lightmaps. The shader doesn't compile and  get an error (undefined varialbe) on the Specular map slot and also on a Fresnel node.
I'm using unity 4.6 as well.

Any idea what the issue could be?

Thanks in advance for the help
