FEM constraints

FEM solver

  • The FEM Solver DOP node now supports animated per-vertex rest positions in addition to per-point rest positions. Also, when Allow Changing Rest is turned on, the restP attribute is now recognized as both a vertex and a point attribute.

  • The FEM Solver DOP node now allows you to use animated rest shapes with the Stable Neo-Hookean Variant material model. You need to turn on Allow Changing Rest to be able to use feature.


  • The new Keep Primitives parameter on the Convert Tets SOP node allows you to keep your input primitives. This provides a simple and efficient way to attach a polygonal skin to an existing tetrahedral mesh.
