<p dir="auto">I'm trying the new C4D 2025 particle system for the first time. I would like my particles radius to follow a curve mapping based on their normalized age, but on top of this, I would like the radius to also be affected by a random noise.<br />
So far I have only been able to do one or the other, but not both.<br />
I tried:</p>
<ul>
<li>using 2x Data Mappers, one set to property with curve remap, second using fields with random field, but either way one of the mappers seems to be overridden?</li>
<li>using 1x Data Mapper, using Source: Property with Noise ticked, noise seems to override the life percentage mapping.</li>
</ul>
<p dir="auto">I want to modulate the size of the particle so it starts 0 radius, ends at 0 radius, but while its alive and radius is above 0, that value should be multiplied by noise.</p>
<p dir="auto">Thank you,<br />
Nik</p>
<p dir="auto">p.s. I was unable to post in the correct category, im not sure why this is showing in site issues, Im also not sure why my account is labled stock-foundation, i dont have control over my company cineversity account setup  so im not sure what the issue with naming/permissions might be?</p>
<ul>
<li>edit, just realised using property + age percentage controlling Radius and Noise Enabled ticked does modify after scaling to get the behaviour I was after</li>
</ul>

Here's an example of using the Data Mapper for the main Curve and then a Math that takes the Radius and multiplies it with a Random number with controls for the frequency (Animation Speed) etc.</p>
