Thanks for all the input guys!
Got it working in the end with just a simple incidence.

Scalar state should be working just fine.
I assume you're trying to compute incidence using a dot product? Make
sure your input vectors are unit vectors and described in the same
coordinate space. Also make sure your vector orientations are
described correctly as well. Remember, the viewing vector is opposite
what you need it to be as it points towards the subject. If you don't
meet those criteria, all bets are off.
If all is correct, the output will be the cosine of the angle between
the two vectors which you may or may not want to linearize for use in
the gradient.

Hey guys
I remember using the scalar state node, with a gradient, to create a
gradient based on incidence... this doesn't work any more??
Am I being dumb, or is it broken?
