Colorjitter controls c4d's own particle colour issues.

[66175545]

Can you please tell me if Colorjitter can control the particles that come with c4d and influence it to produce random colours?

The utility shader might work better.

Thank you for your reply, which is very timely and effective. I would like to continue to ask a question: while using the utility node to achieve random particle colours, I would like to continue to further fine-tune, for example: to adjust the hue, saturation and intensity of the random particle colours, how can I further optimize at this time?

[lee_griggs]

You can add a color_correct shader before the utility shader. This tutorial might also help.

Thanks for replying, but I'd also like more flexible control, such as a jitter node like Redshift's that has the flexibility to read and control particle colours. I hope Arnold has considered this aspect as well.

I did a test with color_jitter here that seems to work.

I believe the color jitter should work fine on particles. How to use it, depends on the instancing mode. If you generate the default spheres or quads, you need to set the parameters under the Face group (as particles exported as points within a single object). If you generate custom shape instances, then you have to set the parameters under the object group (as each instance is a separate object).

How can I set the default particle emitter in c4d and get the desired result? I am a beginner in Arnold and need your help.

Ok, thanks.

Set the Gain/Hue/Saturation under the Object group in color jitter, like this:

Thank you very much for your careful response.
