Filling a volume with stones

[Davers1]

Here you go.

Turn off Particle Physics, Collision (don't mix these with PhysX in the same flow), gravity, and speed.
Increase the PhysX graviry on TyFlow object.
And there you go... no jittering.. nothing.. I even lowered steps to lowest (frame).

I also added time test so I convert particles after 50 frames to completely static.. but you can turn it off basically, because there is no jittering anyway.

P.S. Always when uploading scene for help, save as earliest max version as you can, so more people can help you.

Hope this helps.

Oh, thank you so much! You are my saviour once again   .

I need to buy you a case of beer!

Thanks again,

Andy
