What does it do?

  • Optimization that fixes a long standing bug where your elytra being taken off doesnt make you stop flying

Is this allowed?

  • Allowed nearly everywhere but please ask before using on any servers that aren't on this list or haven't explicitly allowed it.

How to use?

  • Plop into your minecraft mod folder
  • Make sure to have fabric api

Compatibility

  • Should work with any mods that don't edit an elytra's functionality. Might have problems with modded items that allow a player to fly since it won't let you glide without wearing an elytra.

Frequently Asked Questions

Does Hero's Elytra Optimizer need to be installed on the Minecraft server?

No. Modrinth marks Hero's Elytra Optimizer as unsupported on the server side. Install it only in your local Minecraft mods folder. Your server can remain unchanged unless the mod page lists an additional dependency.

Which version and loader does Hero's Elytra Optimizer require?

Use a file for fabric and your exact Minecraft version. Supported versions include 1.21.11, 1.21.4, 1.21.3. Files for different loaders are not interchangeable.

Hero's Elytra Optimizer is not working – what should I check?

First check the Minecraft version, loader version and required dependencies. Put the .jar file in your local .minecraft/mods folder and remove older duplicates. Because this mod is client-side, adding server RAM will not fix it.
