Hello,

First of all, I apologize if my writing is hard to read, as English is not my first language.

I’m currently facing some issues with the particle system in Cinema 4D 2025. Specifically, when particles are generated, the objects associated with the cloner are also generated at the same time.

What I’m trying to achieve is similar to Trapcode Particular’s "Time over Size" behavior, where the particles gradually increase in size from the moment they appear and stop growing once they reach their normal size.

What I have tried so far is applying a Plain Effector to the cloner associated with the particle group, setting the size to -1, and then applying a time field to the Plain Effector. However, this approach didn’t work as expected.

If anyone knows a better way to achieve this, I would appreciate your help.
