Constrain one MPM cloth to another one

verstaerker — Fri, 04 Feb 2022 16:27:51 GMT

maybe my question is a bit noobish .. i just started experimenting with bifrost graph :
I want to simulate a flower with petals.

So i have one geo for the stem and one for the petals , wich both should have different attributes - the stem is more stiff and the petals very soft.
Hoe can i stick the one cloth to the other one ? I know how i can constrain the stem to the ground but i don't know how the petals can be constrained to the top of the stem, wich moves a bit from the sim

this is actually super simple using traditional ncloth and compound constraints ... i'll use that for now . If one knows how to achieve this in bifrost-graph , that be great to know

Hi!

Just connect multiple cloth_source outputs to the mpm_source input of a constrain_mpm node (this even works without any constraint_geometry connected).
