Use a Reference node (
) to refer to another meshing sequence. Building a
Reference node runs the operation nodes of the referenced sequence. If you have a
Scale node before a
Reference node, or as a subnode to a
Reference node, you can create a finer or coarser version of the mesh generated by the referenced sequence.
It is possible to expand a reference (that is, replacing the reference with a copy of the referred sequence). If the reference node has a
Scale subnode, the attribute nodes in the expanded sequence are scaled accordingly. In some cases, such scaling of attributes cannot be done explicitly, and additional scale nodes are created instead.
