    Try changing the particle system's simulation space to local instead of world.

    Anyone know if there's any older *unaffected* versions of 6000.0 URP? I think we're seeing this in 6000.0.56f1 as well.

    It's crazy that this is still happening, and it was posted in the beginning of August.

    Can we please get the Particle System as a package? So we can choose which package version to use, rather than relying on an entire Unity Editor version?

    I've tried opening my commercial project in 6000.3.0b1 to resolve this, but the Editor gives repeating errors (unrelated to this issue), so that's not great either...
