Hi,
I feel like this is a bit of a silly question, but I'm looking at this simple task, and despite all the info found I got stuck.
It's a simple setup just to get the hang of some workflow stuff in H.
I have a grid, with random colors on the primitives, that drive a poly extrusion via a extra attribute. This works just fine, and I get ‘spikes’ with random extrusion heights.
What I want is to add a bounding sphere or some geo shape, that will bring down the color inside the bounding sphere/geo back to black, so the extrusion is canceled out inside there.
I've tried adding and mixing group colors/attributes on the grid colors and bounding sphere color in several ways, but cannot get it to work.
Is this kind of mixing/subtracting colors possible with just groups alone? Or do I have to use VEX shading to get to this result?
thanks!
rob
Q: using/mixing group colors to control e.g. displacement etc.?

Hi,
By using the ‘attribute transform“ node, I found a way where I can use colors from another object.
This will layer the color on top of the existing one, by setting the ’Points” Cd and the “Match P attribute”. After that it's playing with the Conditions ‘Distance Threshold’ and "Blend Width' to get want I want.
It works, but if there's another way I'm all ears.
thanks!

I'm not sure but maybe have a look at the Rohan Delvi tutorials here.

Look for the Recreating Mograph tutorials.
It might help.
