More Information:

At a basic level, Cosmo uses OptiFinearrow-up-right to display capes and cosmetics, therefore it is vital that Optifine (or optifine logic, in other mods) is present on the player's client.

Optifine only works on Forge, however, the Fabric mod OptiFabricarrow-up-right can be used to allow Optifine to run on Fabric (you still require the Optifine Mod too). You need to use OptiFabric (Legacy)arrow-up-right if you are using older versions of OptiFine in 1.14 - 1.15.

When you use OptiFabricarrow-up-right, you cannot use Sodium. You can use the Capesarrow-up-right fabric mod if you'd like to use Sodium but still display capes (cosmetics won't work).
