About this Modpack

The collection is a mods not only on the functions of the bedrock but also on optimization!

The assembly itself is likely to be only for 1.21.5 because it is on this version appeared one mod on a very noticeable feature from the bedrock edition!

Optimization isn't 100% can help increase fps but I try to do otherwise!
!!!The build leaves out some features from Java!!!

Many thanks:

*Server support for Bedrock Edition is available (ViaFabricPlus)

That's all you need to know!

Frequently Asked Questions

JBedrock 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 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 JBedrock 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 €12/month).

Can I add custom mods to JBedrock without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.21.5). 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.

JBedrock server lagging – performance tips

1) Increase RAM to 8 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.
