hi everybody!

i try to bild a dense gravel bed.
i use three vrayscatter systems on a single plane. all settings are the same. they use also the same collosion settings for receive an send collition and the same seed.
the only differend is an other vrayproxy file.
when i render an animation in same frames the distribution is changing to a second state.
i found if i give all three scattersystems a differend seed the issue is gone.
so is it a bug or should i only avoid same settings for seed in this case?

thanks for help.

It not good idea to use the same setting with collisions.
