About this Modpack

Introduction

LMC X-4 is third smallest star known to human-kind, and serves as an extension of SGR-J1935

Instead of only optimizing game (like SGR-J1935), we are also adding quality of life mods, that could help you on multiplayer servers or singleplayer.

Extensions

There are only two extensions of LMC X-4, and you're currently looking at one of them.

SGR-J1935 contains only optimization and doesn't add/change vanilla gameplay mechanics in anyway, which LMC X-4 might do.

Version System

LMC X-4 (and extensions) uses W.X.Y.Z format for release versions.

W will increment each new Minecraft version release.
X will increment with any changes to the list of mods.
Y will increment with any updates to any mods in the list.
Z will increment with any hotfixes to the modpack.

Frequently Asked Questions

LMC X-4 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 LMC X-4 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 LMC X-4 without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.21.11). 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.

LMC X-4 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.
