Hi folks!!
I wondered about this: Is there a way to mask fibers randomly, with an even 0%…100% distibution?
I tried these approaches:
Polygroups/“Group visible” with a low coverage value (repeatedly)
this creates random polygroups fast which I can convert to masks by “Polypaint from Polygroups”->“Mask by Hue”. Problem here is that the random masking is assigned per segment of the fiber, not for the whole fiber.
Polygroups/Auto group
this assigns random groups per fiber (cool) which again I can do “Polypaint from Polygroups”->“Mask by Hue” for to get random masking. This works great but is too slow for like 100.000 hair fibers with 20 segments each. I pressed the button and I’ve been waiting 15 minutes already
(I think I could get away with this when limiting the selection before clicking the button)

:o
Thanks for any tips!
