I made 4 particle systems for one object in order to emit some stones on the ground (smaller and bigger). The system makes stones fall on the ground (with collision). I want to keep all the particles (stones) still at the exact postion (ie. frame 40) but WITHOUT convert operation. Convert operation need tons of additional memory which i don't have (and everything runs super slow). How to "freeze" particle systems without conversion in specific position (frame) so I can run other animation and simulations in the scene?
*or maybe there is another way to generate particles on the ground which are not generated IN the ground (as the plane of ground is crosscutting them in unnatural way).
