Use Reference () 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.

To add a Reference node, choose one of the following:

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.

To expand a reference, right-click Reference node and select Expand ().
