hi every body:
I have a simple problem in recent work.

Is it possible to randomly select 10 points on a mesh at each frame in Houdini? I think it is may be simple, but I can not work it out, hope someone helps. ops:

please.

use Sort SOP with random mode and seed $F
then just select first 10 points by Group SOP (pattern 0-9, point mode)

Alternatively, you can use a Group by Range SOP and play around with a range filter. Possibly also to change it on every frame ($F) and something else.
