Hi, thank you for sharing the feedback. The function UpdateTickWhenPaused() indeed resets the playback of the system. It’s intended to be only called after you spawn a particle system widget manually. If the widget isn’t spawned procedurally but is a part of your user widget I recommend setting the TickWhenPaused property instead. I’ve verified that the warmup time works correctly in both cases. If you’re doing something else and you’re still having the issue please let me know more detailed reproduction steps so I try to replicate it. Cheers!
