By the way, there was an idea to use the "point collision detect" in stop response in the POP Network, but honestly the results are not very satisfied so far.maybe of course I somehow used it wrong, this function))

Buddy, thank you very much for your response and advice! But still, this is not much what I need, It just uses a morph of points and the transition of one point to another by position. I wanted the points that come out of the emitter to direct to the surface. Those I don’t I know how many points and in what position they will come to the surface at the moment. This is the problem (((But thanks anyway !!))

Hello everyone!! There is such a question! YouTube is full of lessons on the disintegration of the surface into particles, but I have another task: I need my particles to leave the emitter, fly and, as they approach, begin to form a surface, as it were. How to do this? as if from the bottom up. I would be very grateful for advice and ideas.

Of course if you want fine control of the curve paths, you can simply use the draw curve SOP to draw your path directly on the geo, and then use the volume velocity from curves SOP to make the velocity fields for your fluid to flow along. EDIT: Whoops I see that Enivob's link used the draw curve tool.

Thank you so much!!

Thanks a lot man!!!

Guys! Hello everyone! Help me approach the solution of the problem. It consists of two stages:
1.Create a curved line projected onto the scan figure in the form of human veins. How to make it?
2. I want liquid to rise from the legs to the head through these veins, along them from the bottom up. What should be the emitter? how to make the liquid move exactly along these vein trajectories?
Unfortunately, I have not found anything like this yet, I will be very grateful for any help!
