Strange Particle System Stuttering at extreme timescales

Questions & Answers
1

I’m working on a Particle System cinematic that happens in super slow motion (TimeScale 0.01). When I use Particle Systems at this speed in the game, the Particle System’s particles don’t animate frequently, in fact they animate less frequently then fixedUpdate (my physics objects animate smoothly at this speed thanks to an increased fixedDeltaTime.)

The weird thing is at some point these particles did work in the sequence, but now the animations appear to only be updating about once every half second.

I’ve tried choking back the TimeScale, and it does start to animate smoothly somewhere around 0.1f. Any idea why this would be breaking down past that point?

Unfortunately, there doesn’t seem to be an option for Particle Systems to ignore TimeScale, but I think if there was, it would solve my problem.

After jerking around with this for a couple of days, I just don’t see anyway to get Particle System to animate correctly at 0.01f. As such, the solution is to bump timeScale up to 0.025f and treat that as your minimum. Below 0.03f timeScale, the animation gets progressively jankier until at 0.01f it stutters like crazy.
