I am following the first steps tutorials, it shows use a metaball spaceship to repel ground particles. When I try to recreate the same effect, the radial force do repel the particles away, but when the spaceship passes by the particles will go back to its original position, which is not what I want. So is this behavior due to the latest update of Houdini, or did I miss something? I have uploaded the scene file, looking forward your thoughts…

this doesn't make much sense, it should do what you expect

if you check Accurate Moves it seems to work correctly, but I would expect it to work even without as well

Hi tamte,
Thanks for your advice. I tried to check the accurate moves, and the particles worked as desired. But if I uncheck it, then they will go back to their original positions. I am running apprentice 12.5.376, may I ask which version are you using?
