Hi bet-beach,

The Smear-Finger idea (Photoshop) was nagging me to translate that to Cinema 4D.

The simple idea is to run a Wind object along a spline and add some other parts to it. Done.

Example:

Yes, it follows the direction even around 180º+ movement.

One more, if particles have moved a certain distance, they go into the Group.2, which means they can be used for additional "effects".

All the best
