OptifiNeoforge Mod (26.2, 1.20.1) – Play NeoForge 1.21 Worlds with Your Own

OptifiNeoforge Mod lets you load OptiFine on NeoForge. Put it and your own OptiFine jar into the mods folder, and it patches OptiFine in at startup. The patched game classes go into the NeoForge transformation pipeline. This mod works on the client side.

Features:

• OptiFine on NeoForge: Loads OptiFine on NeoForge by applying OptiFine’s own patching when the game starts.
• Your Own OptiFine Jar: Uses the OptiFine jar you download from the official site. The mod does not include or share OptiFine.
• One Jar Per Version: Comes as a separate jar for each Minecraft version from 1.21 to 1.21.11. The jars are not interchangeable, and the version is in the file name.
• Feeds the patched game classes into the NeoForge transformation pipeline.
• Uses the same idea as OptiFabric does on Fabric Loader, but with its own code written for NeoForge.
• Needs no installer and writes nothing into your game files.
• Adds its own anti-aliasing post-effect files. The shader stages they use come from the OptiFine jar you provide.
• Contains no OptiFine files, so you can unzip the jar and check it yourself.
• Runs on Java 21 for all the 1.21 versions.
