# Overlap

This tool allows you to add 'overlap' to a chain. Since this tool is still under development, the order in which the chain is selected is important, as the 'overlap' of the curves will be applied in that order.

The tool only works when applied to a single chain at a time.

Shift + Click to create backward overlap or normal click for forward overlap.
