The mod Ears uses blank spaces in the player skin template to both detect compatible skins and to texture the ears/horns/tails the mod adds to player models (note the template from their website I linked below, the colored pixels on the middle-left side and the two additional template boxes between the head/hat area and to the far right of the body/arms area). I attempted to use your mod in conjunction with Ears to create an NPC with cat ears and a tail. The NPC loads my locally-saved custom skin without issue, but the Ears mod isn't detecting the additional textures and the ears and tail remain invisible.

From what I gather on the Ears Discord, the mod works with Taterzens, but I am creating a 1.20.1 modpack and using Easy NPCs. Would you consider adding support for Ears to Easy NPCs? Thanks for your time.

Reference: unascribed/Ears#143

I checked their code base, but found not reference of Ears <-> Taterzens in their code base, which mean it's not a custom implementation and has more do you how the NPCs are rendered instead.

Ears codebase: https://github.com/search?q=repo%3Aunascribed%2FEars+taterzens&type=code
Taterzens codebase: https://github.com/search?q=repo%3Asamolego%2FTaterzens+ears&type=code

Ok. Thanks for looking into it.

I checked this more in detail and "Ears" expect a AbstractClientPlayer and will not accept any LivingEntity which most of the NPCs are.

See: https://github.com/unascribed/Ears/blob/trunk/platform-forge-1.18/src/main/java/com/unascribed/ears/mixin/MixinPlayerRenderer.java

So there is currently no way for me to support the Ears mod, as long there is no possibility to add Ears additionally to LivingEntity instead of only to AbstractClientPlayer.
