Hi there, Quite new to Houdini and trying to create a simple setup of an emitter (lets say a sphere) which produces smoke (simple going upwards) and a box which attracts smoke and gets its volume filled in. I know that someone did something similar in the past: https://vimeo.com/223556457?fl=pl&fe=sh So I am trying to re-create something similar with a simpler setup (sphere emitter and box attractor) with the latest Houdini using latest nodes. I am able to create the sphere emitter (in Geometry -> Pyro Source etc etc) and DOP Network with Pyro solver and Volume Source emitter etc etc... but then I get stuck on how to make the smoke to be attracted to the box. I tried a few things but not getting the desired effect so far. Any idea how I can do this please? Any help would be appreciated! Thanks!!  

Hey, thanks for the reply. The main issue is that it doesn't follow the drawn curves direction/alignment.  Here I drew 2 curves. The branches on the right one should follow the original curve and not stay in the direction of positive z.  Also thanks for the file. I will take a look if I can fit it into my setup.

I can't figure out what you want to do, but I can help you with some tricks anyway. file from Qiita advent 2022   HoudiniAdventCalender2022-20251117T051516Z-1-001.zip

Hi! I have a crowd simulation of ants that idle and walk, they are quite dense packed so to reduce intersections I want some to move on top of the others. Lets say when they are close to eachother I want one of them to move over the other agent. A simple y position change will do it I think. My setup is simple, I have a terrainproject and terrainadaption first to position the ants on the terrain. Then im thinking of using a popwrangle. But wilst thinking it through I see multiple issues, getting the proximity to each other is simple.  But how do I choose which on will move up? And what if mulitple points are in proximity of each other? Does anyone have a good workflow for this?  Thanks!
