Shifting/blurring material between objects I have a feeling this question is either trivial or impossible, but I don't have the blender knowledge to know which.  I have 3 planes all of which share the same material, as shown in the picture below:



The colour is determined by a the random output from object info put through a wave texture and ColorRamp, so that I can randomly change the colours on the different areas by changing the Wave Texture parameters.


I would like to produce an element of blur between these objects.  I would prefer real blur, that is an averaging of two neighbouring colours shifted by an amount in space, but if that's impossible I'd settle for a noise/vector curves method, I'm just not sure if that's possible here either.

Thanks, and sorry if this is a really dumb question.
In your ColorRamp node you can set the mode from "constant" to "linear", then add as many control points as you need to get the desired "blurring".
