OptiFabric Origins (1.14.4 & 1.15.2)

 

These are the old versions of 1.14.4 and 1.15.2 OptiFabric, updated to work again with the latest Fabric Loader and latest supported Fabric API. I've used code and fixes from later versions of the official OptiFabric to patch these older ones. Full credit goes to modmuss50 for creating OptiFabric and Chocohead for maintaining it, without them this wouldn't have been possible.

 

For later Minecraft versions see: https://www.curseforge.com/minecraft/mc-mods/optifabric

For even older Minecraft versions see: https://modrinth.com/mod/legacy-optifabric

 

Important:

- This project does not contain OptiFine, you must download it separately!
- This project is not related or supported by either Fabric or OptiFine.

 

Installing:

After installing Fabric for 1.14.4 or 1.15.2, you will need to place the corresponding OptiFabric Origins mod jar as well as the OptiFine jar from the official OptiFine website into your mods folder. Fabric Loader should be version 0.9 or later (latest successfully tested version: 0.15)
