Find Target (Control by Time) jumps instead of interpolating smoothly - YOHEI MIYAHARA - 09-29-2025 Hi, I’m running into an issue with the Find Target operator in tyFlow. When I set Control by Time (e.g. 20 or 40 frames), I expect the particle to interpolate smoothly towards its target across that time span. However, in my setup the particle does not move gradually—instead it stays still and then suddenly “snaps” to the target position on the specified frame. Here are my key settings: Set Target: Mode = By Proximity, Timing = Continuous Find Target: Control = Control by Time Frames = 40 Ease In = 0% Timing = Continuous Treat post-step particles as new = ON (default) No additional Force operators, just Spawn (By Travel) → Set Target → Find Target Things I already tried: Turning Ease In ON/OFF (doesn’t fix it) Using different distance thresholds Switching Timing between On Event Entry / Continuous Different substeps From what I understand in the docs, Control by Time should make the particle interpolate toward its target smoothly across the given frame range, not teleport at the end. Am I misunderstanding how this mode is supposed to work? Could this be related to the “Treat post-step particles as new” option or operator order in the event? Any insights or a minimal working setup that shows Control by Time working as intended would be very helpful. Thanks!
