Masoud Posted October 27, 2023 Share Posted October 27, 2023 Hi guys In a vellum simulation, I want to un-pin objects over time, using an attribute (I set "stopped=1" on selected points). So I tried to transfer the "stopped=0" attribute, using an "SOP Solver", inside the DOPs. Everything is okay, but in the future, I need more sub-steps, and by increasing the sub-step (to 2 or more), the vellum objects start to jiggle. How can I fix it? Thanks for helping Vellum_Hairs_01.hip Quote Link to comment Share on other sites More sharing options...

Jesper Rahlff Posted October 28, 2023 Share Posted October 28, 2023 (edited) you can also use an intermittent solve dop node after your sop solver and keep the default setting to "solve every 1 frame" if its your sopsolver causing the issues that way your sop solver only evaluates once every frame even though your whole dopnet runs at multiple substeps.
