About this Modpack

This is a Lunar Client alternative modpack, that has almost all the features in Lunar, and even more, allowing you to customize all the individual mods, and even add your own mods!

Why use Comet Client instead of Lunar?

Comet client offers almost all of the same mods, including Essential so a friend system and hosted worlds can be used too! On top of that, you can add ANY mod you want to comet client, meaning there's infinite customizability!

How can I customize the mods in here?

To customize the mods, you can either check with Mod Menu on the home screen or escape screen, or for some mods, it will have a custom keybind which you can find and edit in the controls section.

How can I use the friends system now? How can I host worlds?

Don't worry, Essential has all the same features including a friends+DM system, FREE hosted worlds and more! Your change to Comet Client will be so seamless that you wouldn't notice a difference when playing!

When will it be updated to [insert version]?

When all of the mods this modpack depends on are updated, Comet Client will update as well. We'd love to release as soon as possible, but that's really dependent on the creators of the mods we depend on!

Most common causes: insufficient RAM or wrong fabric loader. Check latest.log for "OutOfMemoryError" → increase RAM to at least 8 GB. For "Mixin" or "ClassNotFoundException" errors: modpack version and loader don't match. With Mado Hosting, loader and Minecraft version are auto-configured on modpack install – preventing most startup issues.

How much RAM does a Comet Client server really need?

Minimum 6 GB, recommended 8 GB for stable performance. per 5 players. Important: Minecraft modpacks need more RAM than vanilla – plan extra per additional player. With Mado Hosting, you can scale RAM up live at any time without data loss (from €7.800000000000001/month).

Can I add custom mods to Comet Client without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.20.4). 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.
