With Obi Softbody you can simulate complex elastoplastic softbodies composed of thousands of polygons, complete with collisions, self-collisions and rigid body interaction.

Softbodies are physically represented by a set of ellipsoidal particles held together by shape-matching constraints. This way, they can deform both elastically (restoring their rest shape) or plastically (absorbing some of the deformation into their rest shape). Version: 7.0.5 (12 Mar 2025)
