This example shows how to generate wrinkles dynamically using the FEM solver. It contains a generic setup, where an object that represents bones and muscles is connected to another object that represents fat and skin. The animation of the bones and muscles object makes the skin wrinkle indirectly. This demonstrates the use of the FEM Solid Object, the FEM Hybrid Object, the FEM Fuse Constraint, and the distributed target constraints that are built-in into FEM Objects.
