Arnold shader

[kokoerico]

Hello all, I require assistance with creating a shader in Arnold.

Essentially, my goal is to implement a gradient across a cloner, while also ensuring that certain objects within the cloner have different colors. Please refer to the attached image. Is this possible using just 1 shader?

I would greatly appreciate any support you can provide. Thank you.

If you can achieve this with Effectors, you can read the color of the clones via the user_data_rgb shader (Attribute: display_color).

You can also read the index of the clones via a user_data_int shader (Attribute: index), which you can map to the [0;1] range and drive a ramp shader or a custom osl shader.
