If the camera is at an angle, or the object is too close to it, it won't work correctly.I thought it was separating the normals forward and normals backward?Haha - that IS from ages ago and I didn't know as much then. That shader is distinguishing not front and back, but whether the polygon is facing +Z or -Z axis. That's not the same as what you want. I can't remember if I found a FireFly solution.
That setup was the first thing I tried, by the way, only with the sign function instead of step.
If I had a node or combination of nodes that gave me the viewing direction as a vector, then I could wire something up in combination with the N node.
