bentraje Posted March 25, 2021 Share Posted March 25, 2021 (edited) Hi, Is there a way to advect points on a SOP level? I understand that there is a VDB Advect Points. I couldn't get it to work. Even if I do, I think its a bit round about way to "advect" points, at least based on the documentation (i.e. uses vdb from polygons, vdb analysis). Just wondering, if there is a simple node/process to do this like the "Pop Advect by Volume" in the DOPS level.

markinglevfx Posted March 25, 2021 Share Posted March 25, 2021 Use the SOP solver and a point VOP/wrangle to sample a vel field at each point's position. You can then add that vector to P to get the next frame's position. advect_in_SOPS_v001.hip 1 Quote Link to comment Share on other sites More sharing options...
bunker Posted March 25, 2021 Share Posted March 25, 2021 just FYI: the solver SOP, is a SOP solver it's using a DOP network inside, so you'll be using DOPs anyways. 1 Quote Link to comment Share on other sites More sharing options...
bentraje Posted March 26, 2021 Author Share Posted March 26, 2021 Hi @markinglevfx @bunker I only have the indie and noncommercial version. So had to ask a colleague to open it for me. The file works as expected. It also works with vanilla volumes (i.e not VDB) although I seem to have more appealing result with VDB. Thanks have a great day ahead!
