Created in Houdini 19.5.303 LC.

Experiments with pop grains - so far compared to my experience with vellum grains, pop grains seem to have more consistent behavior when refining (decreasing particle separation).
The work entitled Peach Powder Puff was created using pop grain with about 1.2 million particles (1,199,079 points), rendered in Redshift.

initial condition

Generally a pre-roll time takes care of the grains, allowing them to settle. There are three approaches that could be taken (possibly others - after all, it is Houdini),
I went for the pre-roll approach.

Of note, I was trying some variations and had simmed out (1.5 days) a version with 4,912,657 points, however the render times I did not have the patience for - perhaps it's time for me to get a new Desktop.
