my results for particle fluid speed stretching are not working out.

specifically, a static number in the ‘duplicates’ is not natural. i'd love to have variation here, but i cannot figure out a rand expression that would limit
the result to a ‘reasonable’ number.

ssetting duplicate to ‘3’ for example triples the number of particles, which becomes unreasonable and looks very unnatural. every particle then becomes EXACTLY 3 points in a row, equidistant from one another.

i've toyed with the stretch ratio and scaling, but have not seen good results yet.

is there a tutorial or resource that offers examples?

anyone with tips?

Often times when I use Speed Stretch, (rarely) I find that I have to use filtering to get a good result out of it.

It slows down a bit from the extra calculations, but depending on the shapes, can help soften the effect.

Good luck!

i did as you suggested. changed to metaballs, and turned on filtering and speedstretching.

the difference was significant.

thank you !
