Hi all, I need to constraint active rbd to static deforming one, but I can't find solution. Its working with animated but not with deforming, I think mane problem that packedfulltransform for deforming obj doesn't change.

The first thing that comes to mind, to me, is RBD Follows Target. Have you checked out this file?
