Mesh Island Node
The Mesh Island node outputs information about separate connected regions, or "islands" of a mesh. Whenever two vertices are connected together by an edge, they are considered as part of the same island, and will have the same Island Index output.
- Island Index
The index of each vertex's island. Indices are decided based on the lowest vertex index contained in each island.
- Island Count
The total number of mesh islands. This is a single value, and does not vary per element.
