Hi.
I'm using Houdini about 1 year. But i really don't know how to create this effect like Reaflow. Can anybody help me? Plz

Somewhere, I think odforce, there is a file that does this. I would do a search for flip fluid follows curve, or something.

It involves creating velocity volumes along along the curve to push the sim, but it works great.
