An easy way to implement resource pack models as hats!
HatCosmetics is a plugin that provides a simple and user-friendly way to implement custom hat models on your server.
HatCosmetics works with no interaction (just toggling resourcepacks) from the end users.
Distribution of hats is handled fully server-side, meaning compatibility and reproducibility with any client.
This is a key difference from mods, which require additional setup for each client.
