Spread particles gradually

[Galea]

If you want to move particles up a certain distance over time, just set the Spread operator value to a fraction of that distance, and then set the timing of the Spread operator (in its Timing rollout) to your distance divided by that fraction.

So if you want to move up 50 units over 100 frames, set Spread timing to frame 0-99 (or 1-100 or whatever your 100 frame range needs to be), and the z-axis spread value to 0.5.

OK, it works!
thank you very much.
actually I would like to understand how I can do a setup similar to this but applied to volumes (the checkerboard in the previous post).
In the attached picture I used tyselect with soft selection on vertices (unfortunately it doesn't allow me to use soft selection on elements) and faceExtrude to extrude them to a certain height.
All this is controlled by the spherical gizmo that scales.
I would like to create this setup not by extruding the faces but by moving the elements up to recompose the plane to a different position on the z-axis. All this controlled by a gizmo or object that scaling creates a gradual effect.
