Align normals to camera with material nodes I am using the Normal Edit modifier (aka Set Split Normals) on directional mode to align an object's normals towards the camera. This gives me some of the shading that I want. However, it causes me to lose access to the unmodified normals, which I need for other parts of my setup.

It seems that it should be possible to get the same effect by using material nodes since we have the camera's view vector from the Camera Data node. I don't understand vectors and the math enough to know what to do with it though. And I'm not clear on what exactly the Normal Edit mode is doing.

Anybody know if this can be done?
Geometry node has an Incoming vector output. That is the vector pointing towards the point the shading point is being viewed from (Blender's manual). If you align surface normals to the camera you also get vectors pointing towards the point the shading points are being viewed from. So that's the same thing. You should be able to just plug Geometry node's Incoming output to Normal inputs of your shaders.
