yujiyuji Posted June 25, 2021 Share Posted June 25, 2021 I want to reverse the direction in which the particles flow in the POP Curve Force. If there is a way to do this, please let me know. Thank you very much. Quote Link to comment Share on other sites More sharing options...
ryew Posted June 25, 2021 Share Posted June 25, 2021 You can reverse the direction of your source curve with a Reverse SOP before using it in the sim and the green arrows of the curve force will show the change in direction, or you can just set the "Follow Scale" attribute to negative values in the Individual Forces tab however, the green arrows will not show a change in direction, although it will work. 1 Quote Link to comment Share on other sites More sharing options...
yujiyuji Posted June 26, 2021 Author Share Posted June 26, 2021 It worked!!! Thank you so much!!! Quote Link to comment Share on other sites More sharing options...
ryew Posted June 26, 2021 Share Posted June 26, 2021 No problem, happy to help. Fortunately, even if the behavior is not documented, some of the nodes in Houdini like the POP Curve Force will accept negative values and behave in a different but still predictable way - it's always worth tinkering a bit just to see what happens!
