Hello;

Particles can follow a path by using “POP Curve Force”…
How could I force particles to move(follow) exactly on a path without any falloff, like image bellow?

Thanks.

I was using the POP curve force node in a pop net recently and had to really wrestle with that network to get what I wanted.

However, this hip file does what I think your asking no problems.

That being said, if you really only want points to move along ‘right on’ the curve itself, maybe a different solution is better than a POP curve force node; Maybe a vex solution?

Otherwise, I would suggest if you have the time, to play around with that POP curve force node for a while under different situations testing results one by one.

There are 3 main tabs, but especially the Individual Forces one and the corresponding tabs with float ramps can be instrumental in giving you an idea of what this node may be good for and maybe what it's not.

Thank you BabaJ;
I add a point wrangle, and I put a minpos() function to force points to stick to curve.

Here is my HIP file:

Great Massoud, thank you.
