So, if local nodes are used, a vertex says node #4, and local node #4 refers to node #5, then the vertex is node #5. There really doesn't seem to be any benefit to using local nodes, considering compressed vertices (which can only address 42 nodes) don't even use them. They just make the models unnecessarily more convoluted while taking up more space."
