Muscle Target Shape
Film/TV

A common request on muscle setups is how to use your own sculpted shapes when a given muscle fires and contracts. This example file shows how to provide an additional sculpted muscle target shape to influence the input muscle through compression and elongation. The technique involves using the FEM Deform SOP and taking the input tet muscle and deforming it by the sculpted target muscle shape with an appropriate attribute used later on in the muscle simulation step. The FEM Deform SOP contains a solver that manages the deformation so that the internal tets remain valid.

    Nice!

    Thanks, Jeff! I usually do the same on my setups using Vellum quasi-static solver with distance attachments. Anyway using FEM should be more precise for the internal tets to not get inversions.
