How to make a crystal material in cycles with the node editor? Much like this -
Not exactly like the image because I'm trying to make an object with a light that is emitting from the center of the object lighting it towards the surface of the object as the light fades. And the object to be crystal like looking (the back faces to be visible too, like a real crystal). The "layer weight" node does something like that, but it shows the materials according to the camera angles and I don't want that. How can I achieve that?
