Mark01 5 Posted December 4, 2020 Hey everyone! I am try to simply advect particles with a moving object. We have particles/grains floating around and a person runs through them at speed so I just need to create some advection/turbulence, more than what's already created from the collision. I assume it is as simple as pyro but I can't seem to work this one out. Any ideas? Thanks Share this post Link to post Share on other sites
bunker 288 Posted December 5, 2020 yes, simple pyro, save your vel field to disk and create a separate dopnet with a popsim and add an AdvectByVolume DOP node There is an example in the docs https://www.sidefx.com/docs/houdini/examples/nodes/dop/popadvectbyvolumes/AdvectByVolume.html 1 Share this post Link to post Share on other sites
Mark01 5 Posted Wednesday at 08:19 PM I'm not sure if this is what I am looking for. Im looking for the object to just disturb the floating particles slightly. Any other suggestions? Thank you!! Share this post Link to post Share on other sites
bunker 288 Posted Wednesday at 08:23 PM (edited) You need to create a smoke sim first, then advect your particles with AdvectByVolume and no need to post the same question twice, thanks Edited Wednesday at 08:24 PM by bunker 1 Share this post Link to post Share on other sites
Mark01 5 Posted Wednesday at 08:26 PM I'm just thinking for pyro, it's simply a case of plugging a vdv in a fluid source. So is there not a more simple method for particles? Share this post Link to post Share on other sites
