Rebuilds captured skins from their simulated tetrahedral cages, every frame.
Physics
Takes the simulation output whole — skins, cages, ground, rigid bodies — and rebuilds every skin geo/cageCapture bound, from the current shape of the cage it was bound to. The two halves find each other through the CAPTURE_ID that geo/cageCapture stamped on both, so nothing has to be routed around the solver. Objects that were never captured pass through untouched; each cage is dropped or kept according to the mode chosen on its geo/cageCapture. Skins are deformed in place, which is what keeps this cheap enough to run every frame.
| Name | Type | What it does |
|---|---|---|
| group | String | Restrict the deformation to a point/primitive group of the skin. Empty = every captured point; the rest keep their rest position. |
| computeNormals | Bool | Update the skin's normals after deforming. They are carried from the captured rest normals through the deformation, which preserves authored normals; a skin captured without normals gets them rebuilt from connectivity instead. |
Scenes you can open in the editor that teach this node.
A sphere dropped as a soft body, so it squashes when it lands. What the solver simulates is a coarse tetrahedral cage, and the sphere you see is rebuilt from wherever that cage ends up.
