OptiBabric (b1.7.3)

This is an OptiFabric fork for Minecraft Beta 1.7.3 and a Fabric fork named Babric.

Note: This project is not related or supported by either Fabric or Optifine.

Note: This project does not contain Optifine, you must download it separately!

Installing

Install Babric in a launcher of your choice that supports MultiMC format instances
Navigate to OptiFine History
Expand Minecraft Beta 1.7.3 spoiler
Choose an edition supported by OptiBabric
Use the Download, Mirror buttons. (Do not use Download 1, Download 2, those are very likely to be dead for all editions)
[Optional] Apply the long distance patch to the downloaded zip
Put the zip in Mods section in your Babric instance settings (or the mods folder), NOT the minecraft.jar
Download OptiBabric and put it in mods as well

During the first launch, OptiBabric will find and transform the OptiFine zip to be compatible with Fabric.

This transformed version can be found at .minecraft/.optifabric/optifine-remapped.jar, but in most cases you don't need to touch it.

OptiBabric will detect if OptiFine was replaced with another edition and will rerun the procedure automatically.

Since this is a fork of OptiFabric, it works similarly, and as such is not automatically compatible with every mod.

If you find a compatibility issue, report to issues
