How to Set Up a Better MC BMC4 Server in 2026

What is Better MC BMC4?

Better MC [FORGE] BMC4 is LunaPixelStudios' vanilla-plus pack for Minecraft 1.20.1 Forge. It adds better world generation, structures, dimensions, mobs, quality-of-life changes, quests, and multiplayer-friendly adventure systems while still feeling like Minecraft.

That makes it one of the easiest modpacks to recommend to mixed-skill groups. New players can explore and build without learning complicated machinery, while experienced players still get dimensions, gear, bosses, and long-term goals. If ATM10 feels too heavy and Homestead feels too cozy, BMC4 sits right in the middle.

Which Version to Run

Use the latest BMC4 Forge 1.20.1 release and the matching server pack. CurseForge currently lists BMC4 v58 with a matching server pack for Minecraft 1.20.1 Forge, so do not mix it with BMC5, BMC3, Fabric, or NeoForge variants.

Minecraft 1.20.1 Forge servers should run Java 17. If your host defaults to Java 21 because newer 1.21.x packs use it, switch the runtime before booting BMC4.

RAM and Requirements

BMC4 is easier to run than giant kitchen-sink packs, but it loads a rich overworld and a lot of exploration content. Give it enough RAM to breathe, especially if your players spread out.

Quick Setup with ModReady

ModReady is the simplest path if you want the pack online quickly:

1. Choose the Standard plan for 8 GB RAM.
2. Select Better MC [FORGE] BMC4 in the modpack picker.
3. Pick a server region near your group.
4. Use WELCOME20 for 20% off the first month.
5. Share the server IP once the first boot completes.

The biggest benefit is version matching. BMC has several similarly named branches, and ModReady keeps the server pack aligned so your players are not joining a BMC4 server with the wrong client generation.

Self-Hosting Steps

1. Install Java 17. Verify with java -version.
2. Download the BMC4 server pack from CurseForge. Use the server pack, not only the client modpack.
3. Extract into a clean folder. Keep one folder per modpack version.
4. Run the included install/start script so Forge and dependencies are created correctly.
5. Accept the EULA and restart the server.
6. Open port 25565 if you host from home. Our port forwarding guide explains the router side.

Recommended Server Settings

Start conservative. BMC4 looks great at high distances, but server TPS matters more than a long horizon.

view-distance=8 simulation-distance=6 max-players=10 online-mode=true spawn-protection=16

If your group is exploration-heavy, pre-generate the area around spawn. If lag appears later, use our lag guide to profile before raising RAM or adding extra performance mods.

Common Issues

• Wrong Better MC version: BMC4, BMC5, BMC3, Forge, and Fabric are not interchangeable. Match the exact branch and release.
• Java mismatch: use Java 17 for BMC4 Forge 1.20.1.
• Players time out when exploring: lower view distance and pre-generate chunks near common travel routes.
• Server pack missing client mods: that is normal. Do not use a server pack as a player client install.
