Frequently asked questions

How do I know OptiFabric is actually working?

Launch the game with Fabric and check the main menu or the mods list for OptiFine's own options button, which appears when OptiFabric has successfully loaded OptiFine. If you see the OptiFine settings screen and the zoom key works in-game, it's running.

Why does my game crash when I add OptiFabric to my modpack?

OptiFabric conflicts with other mods that patch the same rendering or entity code, most commonly Sodium, Iris, and other performance mods. Remove or replace the conflicting mods, since OptiFine and those alternatives cannot run together.

Can I use shaders with OptiFabric on Fabric?

Yes, OptiFabric loads OptiFine's shader engine, so you enable shaders through the OptiFine video settings menu and drop shader packs into the shaderpacks folder. Make sure no separate shader mod like Iris is installed alongside it.

How do I zoom in with OptiFabric?

OptiFine's zoom is bound to a key you can set in the controls menu, and holding it zooms the camera while you look around. If zoom doesn't work, OptiFine likely didn't load correctly through OptiFabric.
