Find out which Clients/Mods are compatible with Cosmo Instances.
Cosmo has been discontinued. Support will not be given. This documentation is only here if you wish to continue using Cosmo and for the sake of internet history.
Due to how Comso works & serves cosmetics, and how vast the Minecraft modding landscape is, there are some compatibility issues with it. You can find these below. If you are using Cosmo, use the information below to tell your users which clients are compatible.
At a basic level, Cosmo uses OptiFine 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 OptiFabric can be used to allow Optifine to run on Fabric (you still require the Optifine Mod too). You need to use OptiFabric (Legacy) if you are using older versions of OptiFine in 1.14 - 1.15.
When you use OptiFabric, you cannot use Sodium. You can use the Capes fabric mod if you'd like to use Sodium but still display capes (cosmetics won't work).
