Color user Data on CLones

[MaverickMongoose]

Hi Dr Sassi, I'm trying to apply random colors to clones in Redshift.

I've made a Redshift Material with a Color User Data (set to Index Ratio) plugged into a Ramp with 8 colours.

On 8 clones in a cloner set to linear, each color is applied as expected.

However if the cloner is set to a grid of 8 instead the colors arent applied one after the other, it just takes the two end colors of the ramp.

Any idea how I can make it work correctly on a grid of clones?

Thanks again🔒 Log in to view

Hi MaverickMongoose,

Thank you very much for your file.

The answer is based on the idea that the Matrix sequence would change a lot if animated (Count), perhaps only on one axis; nearly all IDs would change, even with minimal changes.

If you like to continue the ID flow, a little extra work is needed. The Matrix Object delivers the Matrix, and the Cloner shares the ID for every single clone.

Here is your file
CV4_2024_drs_24_MGmi_01.c4d

Here is an animation with the flow set up, animated
CV4_2024_drs_24_MGmi_11.c4d

Is this working for your project?

Cheers

Thanks for that. I thought it might be easier to do! Shame it needs Xpresso, I never would have thought to do that.

Good to know though, I'll see if I can apply that to my project.

Thanks again!

Is it possible to randomize the colors with this setup so they arent all colored in a row like that?

Hi MaverickMongoose,

Thank you for the reply.

The XPresso was used to keep it comfortable, just having the numbers in sync.

To have the colors randomized, I would just use a Random Effector.

This is much easier to set up directly, and you can influence the overall color/contrast/saturation with the Random Effector>Effector> Min/Max.

The other example uses a Color Correction Node to have more control over the setup.

Please let me know if that works for you.

All the best

Brilliant, thanks again!
