Using OptiFine as a Mod

This refers to using OptiFine as a mod with Forge, FabricMC, or as a jar mod, not using OptiFine in general.

---

FabricMC

1. Install FabricMC
2. Put OptiFabric in the .minecraft/mods folder
3. Put OptiFine in the .minecraft/mods folder
4. Troubleshoot if necessary.

Notes

• If using OptiFabric on 1.18.1, OptiFine release H4 must be used. If not, the loading screen will loop or the game with crash outright.
• Fabric API version 0.51.1 1.18.2 to Current (As of 5/6/22) is incompatible with OptiFabric. If Fabric API is required by another mod, Fabric API 0.51.0 1.18.2 or below should be used.
• If using the CurseForge launcher, that instance’s mods folder should be used instead of .minecraft/mods.

---

Forge

1. Install Forge
2. Put OptiFine in the .minecraft/mods folder
3. Troubleshoot if necessary.

Notes

• OptiFine doesn’t appear in the mods list. If the user asks, tell them to go to video settings and check for the OptiFine watermark in the bottom left of video settings.
• If using the CurseForge launcher, that instance’s mods folder should be used instead of .minecraft/mods.

Jar Mod

Warning: Obsolete - Will be updated soon

1. If the user is on H1_pre2 or lower, skip to step 5
2. Ask the user to press “Extract” in the installer.
3. Run !jarmod and ask the user to follow the steps
4. Ask the user to select all the files while still inside the OptiFine mod folder, and then send them to a zip file.
5. For MultiMC, add the jar mod to the Minecraft jar using the menu. On other launchers proceed as normal for installing jar mods on that launcher.

Troubleshooting

1. Check if the game crashes with only OptiFine/OptiFine and OptiFabric in the mods folder
2. If not, run !tm to guide the user on how to find the incompatible mod. If it does, troubleshoot OptiFine/Optifabric
