FGenerateSurfaceBindings | Unreal Engine 5.7 Documentation

API > API/Plugins > API/Plugins/ChaosFleshNodes

Generate barycentric bindings (used by the FleshDeformer deformer graph and Geometry Cache generation) of a render surface to a tetrahedral mesh and its surface. If a point is outside of the tetrahedral mesh, find surface embedding within SurfaceProjectionSearchRadius. Embeddings of LOD 0 are color coded in the render view: green: embedded on in a tetrahedron blue: embedded on a surface triangle red: orphan (cannot be embedded) yellow: orphan reparented to a tetrahedron from a node neighbor
