The idea is simple , and is based on a Resource Pack I have installed and use frequently. Tools that Diminish over time based on durability but it is visualized so you can somewhat see the damage.

An image for reference, it is also from the Vanilla Tweaks Resource Pack. I know this is asking for A LOT (Or at least I assume) So no pressure at all. Just would be nice to see this same effect applied to your lovely Variants.

this is something still on my radar, but it is an incredible amount of work with little benefit to most.
by all means create the textures for me 😂
