Also you can use a combination of these factors with the mix color or the band node.

You should calculate dot product between (shading normal vector) and normalized(camera_position - shading position).

I hard-coded the position of a camera.
It would be great if we could get the camera position and calculate a normalized vector from nodes.

Hi SlowHand

I will create the setup and play around with it quite a bit to try and get an understanding of what the nodes are actually doing. I'm a bit out of my depth at the moment. :oops:

Many thanks :D
