Hi all! I have some of this working but Im not quite sure where to go next. I have created a top to bottom ramp in vert colours which I want in the red channel. I have ambient occlusion in the green channel and a random colour effect in the blue channel. BUT I cant figure out how to combine the channels. Problem, when I generate random colours it affects all channels where ideally I would like to randomise only the BLUE channel. Same when generating the colour ramp, I only want it to affect the RED channel. Im poking around at VEX and trying an approach with a Vertex VOP but I dont know enough about either to make it happen. All help appreciated, even if its just advice on the approach to take!
Cheers!

The quickest way to do this is probably a bit of VEX. If you generate each of your three color channels as separate float attributes, you can combine them together with a wrangle. The exact code would depend on what your various vertex attributes are named, but it'd look something like this:
@Cd = set(f@ramp, f@occlusion, f@rand);
