About this Modpack

JSMC Modrinth header

A modpack to enhance vanilla Minecraft.

This pack includes:



Lots of simlpe texturepacks to refresh things that alredy in the game.



Lots of mods to improve the visuals of Minecraft while still maintaining the vanilla atmosphere of the game.



Many time-tested mods that stably improve performance of the game even on weak computers.



P.S. This is basic mods, texturepacks and shaders that I'm using in my every personal modpack, so I finally decided to collect them all in one place. Hope it will be useful for someone. Enjoy.

Frequently Asked Questions

JSMC 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 JSMC 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 JSMC without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.21). 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.

JSMC 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.
