Open MultiMC and create a new instance, picking the same Minecraft version as before. However we’re using MultiMC, so we want to Extract, which will give us the actual drop-in mod jar that we can load into MultiMC.Īt this point, we now have two files for Optifine: the original installer and the new “OptiFine_1.14.4_HD_U_F5_MOD.jar”.

If you were to continue using the vanilla launcher, you could click the Install button. Having the Optifine jar downloaded (in this case, it would be named OptiFine_1.14.4_HD_U_F5.jar), run it directly by either double clicking it or invoking it from a command line. If it hasn’t already downloaded minecraft.jar for this version, it will do so, and then launch the game. Run the new installation to download that version of Minecraft from, then exit. In the vanilla launcher create an “installation” of the Minecraft version for which you are running the shader.

Therefore for now it will only support Fabric as a mod loader/API, and cannot load Optifine without Optifabric. Optifabric – MultiMC refuses to kowtow to the whims of Forge incompliance.Optifine – Pick the latest build for the version being played ( ).

Vanilla Launcher – Optifine needs this to extract the actual mod from the mod installer that it distributes.

Specifically since I started playing again in a major way from v1.14.4, installing mods is not as simple as it used to be, and Optifine is no exception, especially when it comes to a third-party launcher like MultiMC. Gathering all of the resources of the Internet, I finally pinned down the technique to install an Optifine shader in an instance of Minecraft from the MultiMC launcher.
