Hi ,
Sorry to reply you so late because I was on a vocation ^^; For the the field you mentioned in the video, I think it’s not a problem to simulate that in Houdini. It seems like particle follows a spiral path. When I got some time, I can try to make a similar one in Houdini and use the tool to export the vector field then import that into Unreal Engine just like the video does. Once I’m done I’ll send you a sample file and you can try it by your own and see how it goes
Sincerely,
