Toon UV Discard

A Toon shader with support for hiding parts of the mesh based on the UV tile they're in

UV Discard in Action

UV Discard might be an intimidating concept at first. But if you are comfortable doing simple edits in blender you should be able to use this technique without issue!

The core idea is to optionally hide anything that exists on a particular UV "tile". Usually, UV coordinates in something like Blender only go from 0 to 1, but nothing stops you from putting things beyond that range.

This shader takes advantage of that and the fact that when shifting by whole values (1, 2, 3, etc) the UVs will wrap around.

Altogether, this allows you to offset UVs of, for example, your jacket or boots by a 1 on X axis, and then hide them by toggling Hide 1 in the UV Discard options

The shader also encourages the use of unused UV maps on your model so you dont even have to affect your main UVs to leverage this technique.

While it might look more complicated than a blend shape or just a toggle approach, it is generally more performant than either of those, so I encourage you to try!
