Some Particle Systems glitching for unknown reason only in render I recently created an animation with 4 particle systems and some force fields. It starts out correctly, but at ~frame 60 one of the particle systems starts glitching like this:
Frame 65

Frame 66

Frame 67

Later this happened to the blue and white particle systems as well. I have attached the full 630 frame animation and the blend file. Sorry that it is in the video sequencer screen.

I can't reproduce your issue ... so I would say for two reasons

Enable Output Properties &gt; Output &gt; Image Sequence &gt; Overwrite
or try under Particles Properties &gt; Cache &gt; Delete All Bakes and Bake All Dynamics again
