I was wondering if anyone knows a material or shader that can be seen through any object like the builtin font material.
Actually, you can use the textShader… I’ll have to check out the code for it so I know what to add to my other shaders, for some reason using the textShader for something that’s not text sounds like a bad plan.
Nah, I’ve done just that once or twice. All that matters is what the shader does, not what it’s called. 
Text in Unity is, after all, just a bunch of UV mapped polygons.
