About this Modpack

Kosmopack!

Quality of Life, client-only modpack for vanilla players. Made with friends in mind.

  • Keeps the game vanilla - you can still connect to vanilla servers and play vanilla game.
  • The pack is intended to be non-invasive and playable out of the box.
  • No new blocks are added; the pack is just quality of life (and sometimes arbitrary weirdness).
  • All mods can be enabled/disabled to suit your taste and needs.

Optional Mods

Some mods are disabled by default since they change the way you interact with the game in ways that might be considered disruptive if you're not used to them. These include Itemscroller (changes bulk inventory operations), Entity Culling (might cause entities to disappear when using freecam) and others. Check the mod list if you're interested in those extra mods.

Migration

When migrating from a previous version of the modpack you can copy all your settings & saves so there's less time spent configuring things.

Copy the following files/folders from the old instance to the new instance; when asked, choose "Overwrite":

  • journeymap
  • voxelmap
  • config
  • itemscroller
  • options.txt
  • optionsof.txt
  • saves
  • schematics
  • screenshots
  • servers.dat
  • XaeroWaypoints
  • XaeroWorldMap

It's okay if some files/folders are missing in your instance.

Source Code

This pack may contain custom builds of mods, especially whenever a new Minecraft version lands and official ports are not available yet. These mods are marked with Kosmolot in the version number. Source code for the ports is available on my Github account.

Frequently Asked Questions

Kosmopack server crashes or won't start – what to do?

Most common causes: insufficient RAM or wrong fabric loader. Check latest.log for "OutOfMemoryError" → increase RAM to at least 6 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 Kosmopack server really need?

Minimum 4 GB, recommended 6 GB for stable performance. per 8 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 €8/month).

Can I add custom mods to Kosmopack without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.19.4). 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.

Kosmopack server lagging – performance tips

1) Increase RAM to 6 GB+. 2) Reduce server view-distance to 8 (server.properties). 3) Pre-generate chunks with the "Chunky" plugin. 4) Use /spark profiler to check which mods consume the most tick time. With Mado Hosting, all servers run on NVMe SSDs with dedicated CPU cores – eliminating hardware as a bottleneck.
