About this Modpack

This modpack contains to key categories of mods: Performance optimisations and quality of life (QOL).

This is not a typical modpack: You can use it to play on most online vanilla servers. It simply improves the client. It contains a lot of mods that I find useful for playing on public minecraft servers. But caution: some servers might deny using a minimap, so be aware of that!

CAUTION: 4GB RAM is mandatory to run!
Instance > Settings > Java and memory > Custom memory allocation => 4096

The modpack contains mods for:

Litematica: To work with schematics
Iris: for Shaders
Performance mods
ViaFrabricPlus: To be able to join on servers on lower versions
Simple Voice Chat
REI: The mod you know, where you can see every crafting recipe in the inventory
Distant Horizons (powerhungry but an insane quality improvement)

and many, many more.....

Can I add custom mods to Crafters Optimisations + QOL without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.21.4). Common issues: ID conflicts with recipe mods and incompatible coremod versions. The Mado dashboard mod browser only shows compatible mods and warns about known conflicts.
