Dex Cosmetics
by Dexzys
On a server running Dex Cosmetics, players can wear hats, back items, capes, wings and backpacks, carry item skins, and show visual effects, and none of them needs to install anything.
What it does
Cosmetics are defined one JSON file per item and sorted into four subdirectories by type: hats and head equipment, back items such as capes, wings and backpacks, held-item skins, and effects such as particles, glow and snowstorm particles. Each type is rendered according to its own rules, so a hat is placed on the model's head display transform while a back item only reads a uniform scale value.
Players do not install anything. The server serves its resource pack through Polymer's automatic hosting, and vanilla clients receive it when they connect. Clients that decline the pack are kicked, unless the server sets the requirement to false, in which case those players see vanilla content without the cosmetics.
Dex Cosmetics needs Fabric API, Fabric Language Kotlin, Polymer and Text Placeholder API, and the mod jar goes into the server's mods folder along with those dependencies. It is published for Fabric only, for 1.21.1, with 1.0.3 as the latest file. It is server-side only, and the mod is licensed under the GNU General Public License v3.0 only, which means it is not open source.
Key features
Hats, back items and capes
Head equipment, back items, capes and wings can be assigned to players as cosmetic slots.

Effects and particles
Visual effects include Bedrock-format particles, glow outlines and snowstorm particles.
Permission-based admin commands
With LuckPerms installed, admin command access can be granted by permission instead of requiring operator level 4.
