Particle system issue - hair moves at the start of animation even without force fields I have a sphere with a hair particle system.
gravity ON, stiffness 2.500, cache start: -200

I tried to play my animation without force field enabled, the particle system is moving (for sure it could be the gravity influence).
How can I see if I set the cache start at -200 the problem is still there or not.

How can I stop this animation and then be able to move the particle system without problems?
I'm not sure if this is what you're asking... but if you move to frame 0 it will reset it, unlike moving to frame 1.

Hope this solves the issue you were having!
