Move Particles Along the Surface of Objects | Houdini 19

The other day I saw an effect where particles were moving along the surface of geometry. It was done using Cinema 4D and Xparticles. I decided to recreate this effect using Houdini. In this video we go over how to move particles along the surface of objects using Houdini 19 and render using Redshift.

I really liked the Popwind and the Ray inside the popsolver with the object merge, I really didn't know. thanks

That looks pretty interesting. Thanks for sharing. The solver sop in Houdini is simply amazing.

Thank you for this Stormz!
A little addition: in the Trail SOP you can change the mode to Connect as Polygons and disable Close Rows. This way the Add SOP is not required

hi, I have a question it works perfectly but when I use cache node after popnet and then use de trail and add node doesn't work I can't see anything?

Вот это ты человек вообще, так помог! Спасибо!

What if I wanted to add static bubbles inside an animated alembic using pop networks, how could I do it?

[Bolaway]

And what do I do when I have a animated geometry and the trails compute this deformation

Hi! Thanks for the amazing tut! i was wondering, i did everything as you described. Set up my render, and from frame to frame it gets slower and slower, once the srtands kick in, dont get me wrong, the frame render time is 15 sec, but the "extracting light objects and extracting proxies" takes up exponentially big time gaps (i dont have any lights, nor proxies in my scene). am i doing something wrong? thannks!

Mac or PC to learn stuff in this playlist?

This works within the sopsolver but is broken when I step out into the popnet- the sopsolver is ignored. Why is this not working on 19.5.640?

Hi, I would like to know how I should import and export attributes between the nodes parameters.

I already understood the groups 100%, but I don't have the same ability with the attributes.

the interesting to my is: "each node has its attributes, up to three or four or more, but I feel dizzy, I don't understand well when change, import or export them and I need a guide".

This is great, the ray sop does the trick but how to change the speed of the particles after that? None of the pop forces seem to work anymore after the ray sop inside the sop solver.
