About this Mod

Rocket Utlis

This mod turns off unnecessary (in my opinion) interaction with rockets:

Sneak-only interaction
Using through grass and other non-colide blocks

Lithium compatibility

Some things don't work by default if you use Lithium. To fix this, open the .minecraft/config/lithium.properties file and add to it:

mixin.world.raycast=false

Rocket Utils server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.6). You can switch loaders with one click in the panel.

Server lagging with Rocket Utils – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Rocket Utils consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
