This auto-action creates underfill lineart automatically.

How it works:
It duplicates the selected layer, reduces it luminosity to 0 (Black) and expands thickness.

It is recommended to place the underfill layer behind all others to get that hidden line effect but it also works as a clean lineart on it's own. It is especially efficient for creating VTuber Models flats layers.
Enjoy!
