Arcmetica for PojavLauncher

Our good friends at PojavLauncher have already patched their client for you! Just play with Optifine and our capes and cosmetics will come through.

If you're using Fabric on PojavLauncher, you can use our mod for more features.

 

Method 1 (Mixmetica)

This method requires you to use Optifine on Forge 1.8. Download the Mixmetica Forge mod here and add it to your mods folder.

 

Method 2

This is the best way to install Arcmetica when you use Optifine but not Forge 1.8. Make sure to disable and uninstall other cape services like Cloaks+ or Mantle before proceeding to install Arcmetica.
