Troubleshooting

The command is not working

Make sure you joined a singleplayer world. The commands are not available in multiplayer.

Check config/defaultoptions of your instance for the generated files.

First-run defaults only apply cleanly when the target files do not already exist yet.

If you are testing changes, use a fresh profile or remove the local files you want to re-seed first.

The path inside config/defaultoptions/extra must mirror the real Minecraft game directory.

For example, JourneyMap files belong under config/defaultoptions/extra/journeymap/....

Also note that extra is never auto-generated by the save commands. You must copy those files in manually.

Some launchers populate an options.txt themselves, which means Default Options won't apply its own defaults.

Check your launcher's documentation for how to disable global options.

If the pack uses FoamFix Anarchy Version, disable B:initOptions in the FoamFix config. Otherwise Default Options will not initialize correctly.

Commands

Default Options writes packaged defaults into config/defaultoptions when one of the following commands is run.

Configuration

Configurations are located in your instance's config folder and can be edited with a text editor.
