In this case - I created 3 colour ramps (R, G and B) based on this graph from the link below [image] [image] http://markkness.net/colorpy/ColorPy.html I then added them together using the layer weight node key the observed thickness as a function of viewing angle. I wonder if it might be possible to recreate the graph using a simple math function for each RGB component, rather than using colour ramps. The three RGB components appear to be based on a sine w…
