JSON patch for MultiMC for Optifine 1.14 Minecraft

optifine.Optifine.json

{
    "+tweakers": [
        "optifine.OptiFineTweaker"
    ],
    "formatVersion": 1,
    "libraries": [
        {
            "name": "net.minecraft:launchwrapper:1.12"
        },
        {
            "MMC-filename": "OptiFine_1.14_HD_U_F1_pre2.jar",
            "MMC-hint": "local",
            "name": "optifine:OptiFine:1.14_HD_U_F1_pre2"
        }
    ],
    "mainClass": "net.minecraft.launchwrapper.Launch",
    "name": "OptiFine",
    "requires": [
        {
            "equals": "1.14",
            "uid": "net.minecraft"
        }
    ],
    "uid": "optifine.Optifine",
    "version": "1.14_HD_U_F1_pre2"
}

Alright, I found a fix for 1.14.4_HD_U_F2_pre1:

1. Have Minecraft 1.14.4 installed on the default MC launcher.
2. Run the OptiFine installer and extract, then move the extracted JAR to your instance's libraries folder and remove the "_MOD" suffix from the filename.
3. Run the OptiFine installer again but now Install OptiFine for default MC launcher.
4. Go to %appdata%\.minecraft\libraries\optifine\launchwrapper-of\2.1 and copy the JAR to your instance's libraries folder.
5. Go to the Version tab for your instance in MultiMC.
6. Add Empty
   Name: OptiFine
   uid: optifine.Optifine
7. Edit it
8. Paste the following into the file

{
    "+tweakers": [
        "optifine.OptiFineTweaker"
    ],
    "formatVersion": 1,
    "libraries": [
        {
            "MMC-filename": "launchwrapper-of-2.1.jar",
            "MMC-hint": "local",
            "name": "optifine:launchwrapper-of:2.1"
        },
        {
            "MMC-filename": "OptiFine_1.14.4_HD_U_F2_pre1.jar",
            "MMC-hint": "local",
            "name": "optifine:OptiFine:1.14.4_HD_U_F2_pre1"
        }
    ],
    "mainClass": "net.minecraft.launchwrapper.Launch",
    "name": "OptiFine",
    "requires": [
        {
            "equals": "1.14.4",
            "uid": "net.minecraft"
        }
    ],
    "uid": "optifine.Optifine",
    "version": "1.14.4_HD_U_F2_pre1"
}

And you're good to go!

This is what works for me:

1. Extract Optifine and let it save as OptiFine_xxxx_MOD.jar (yes you have to make a 1.14.4 profile with the Minecraft.jar official launcher first)
2. Go to MultiMC and Edit Instance
3. In Version section click Add to Minecraft.jar and select OptiFine_xxxx_MOD.jar
4. that's it, launch!

MultiMC saves the optifine's jar in /jarmods and creates the patch at /patches

I just tested with OptiFine_1.14.4_HD_U_F2.jar and everything worked just fine.

I have been looking for a solution and this worked perfect for me. It worked for OptiFine_1.14.4_HD_U_F4.jar
