About this Mod

RLMixins is a mixin tweaker mod with patches and tweaks for the modpack RLCraft.

Sister mod of FermiumMixins (https://modrinth.com/mod/fermiummixins) which is a more general purpose tweaker mod meant for general modpack use.
Both mods can be used at the same time and are fully compatible.

RLMixins currently contains over 30 different patches designed for the modpack RLCraft.
While designed for RLCraft, all patches are still designed to be compatible in other modpacks if desired.
Every single tweak is toggle-able in RLMixins' config and includes simple mod compatibility warnings.
By default all config options are disabled for full compatibility with other mods.

Frequently Asked Questions

RLMixins server crashes on startup – what to do?

Most common cause: wrong forge 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 (1.12.2). You can switch loaders with one click in the panel.

Is RLMixins compatible with forge?

RLMixins officially supports forge for Minecraft 1.12.2. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with RLMixins – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if RLMixins 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.
