-   Three node setups to illustrate the effect of Group ID. 
-   In the first, the 4 curves share the same Group ID, resulting in 1 mesh island.
-   In the second, the 4 curves have a different Group ID, resulting in 4 mesh island.
-   In the third, the 4 curves are seperated in two group based on their position, resulting in 2 mesh island.
+   Here, 300 single curve point are joined to the star primitive to customize the triangulation.

+Group ID
+--------

+The following figures display diverse application of the Group ID.

+.. The following example were made with some nodes "hidden" to illustrate the amount of mesh islands
+.. and avoid Z fighting.
+.. Mesh Island Index -> Set Position (as z offset) 
+.. Mesh Island Index -> Map Range (Mesh island count as input max) -> Color Ramp (distributed from left)
