Hey guys!
This one was requested quite a few times so here we have it :)
I saw the beautiful mix of vellum (or flip) fluid and rbd done by ruye_ruye a while ago and also recent artwork by Simon Reher reminded me that vellum fluid might not be only grains or meshed fluid haha, so here I mixed viscous vellum sim and used its velocity to drive some rbd nuts! Also used some new tricks for texturing :)
