Can shuffle or seed value from Random output.
Thank you very much.
For this kind of thing, 2.81’s white noise ought to be great (but haven’t tested it yet). Ideal way to do this is to create a vector for a white noise lookup consisting of (object index or random, seed2) and use that instead of random.
Can do this with a regular noise node too, which is often cool as you can get soft transitions if you want, but you don’t end up with evenly distributed values. Would want to run output through a curves node on the way to the color ramp and tune to eye to get something approaching even distribution.

I think white noise node should be set to 1D in this case.
I believe I’ve seen it go a bit weird if expected input is not provided.
