Hi guys i´m trying to constraint an RBD packed to a RBD packed flagged as static deforming
and i´m getting a lot of problems , mainly the active pieces will not follow the static deforming at all the constraint just streches as crazy any ideas

working on housini 14.0.361

was it “working on housini 14.0.361” or are you “working on housini 14.0.361”
can you share an example file :-?

Maybe switch from Bullet to RBD as Solver.
When using Bullet, fiddle with the Physical Properties of the dynamic object.

see notice in AutoDopNetwork…

definitely post your scene or similar one, but if you have deforming rbd where all motion is from deformation then you need to constraint to the actual points and not to the rbd object itself as rbd object is not moving, the link you are seeing is probably just visual line to center of mass

but again, without scene is just a guess

Hi guys thanks a lot i will prepare a test scene and upload
