Better MC modpack Minecraft server

Better MC is a "vanilla plus" modpack line from LunaPixelStudios. Its CurseForge pages list overhauled world generation, new structures and bosses, and quality-of-life mods. The line is numbered BMC1 to BMC6, and an edition can come in a Forge, Fabric or NeoForge version, each as its own CurseForge page. This guide covers two of them, BMC4 for Minecraft 1.20.1 on Forge and BMC5 for Minecraft 1.21.1 on NeoForge, and you install either from the Modpacks tab.

Checked against Better MC BMC4 v62 and v62hf on Forge 47.4.20 and Minecraft 1.20.1, and BMC5 v53 on NeoForge 21.1.250 and Minecraft 1.21.1, October 2026.

Which edition to install

• Better MC [FORGE] BMC4. Minecraft 1.20.1, Forge 47.4.20. The page lists 350+ mods and 100+ quests. The server pack's mods folder holds 318 jar files, plus 58 more that it ships switched off as .jar.disabled. Java 17.
• Better MC [NEOFORGE] BMC5. Minecraft 1.21.1, NeoForge 21.1.250. The page lists 320+ mods. The server pack's mods folder holds 289 jar files, plus 61 more that it ships switched off as .jar.disabled. Java 21.

BMC1 to BMC3, and the Fabric editions, also have their own CurseForge pages, and this guide does not cover them. A newer one, Better MC [BMC6] for Minecraft 26.1.2 on NeoForge, has its own page too, and this guide does not cover that either. Pick the edition that matches the Minecraft version your players want, because the loader and the version are not interchangeable. The versions above are named in each server pack's variables.txt, and the panel switches Java for you.

What the pack needs

• Memory. Neither page gives a figure. Each server pack's variables.txt asks for a 4 GB heap (-Xmx4G), but the panel does not read that file. It sizes the heap from your plan's RAM at every start. Read how much RAM a Minecraft server needs and check the Minecraft plans before you install.
• Disk space. The BMC4 server pack is a download of about 1 GB and unpacks to about 1.1 GB, so allow about 2.2 GB free. The BMC5 server pack is about 663 MB and unpacks to about 714 MB, so allow about 1.4 GB free. The download is deleted afterwards, and your world grows on top. The Disk Analyser tab shows what is using space.
• The same pack version for players. Players should run the same edition and version from the CurseForge app.

Install the server files

Press the CurseForge chip above the search box and search for Better MC. Press Install on Better MC [FORGE] BMC4 or Better MC [NEOFORGE] BMC5, both by LunaPixelStudios. Other packs share the name, so check the author and the edition in the title. The popup names the loader and Minecraft version. For the rest of the window (the version list, the backup and the EULA), see Install a CurseForge modpack.

The server packs ship mods and configs but no loader jar. The install reads variables.txt from the pack and installs the loader build it names. A file with no server pack names its loader build in its manifest.json, and the install uses that.

For BMC4, Newest that fits your server takes v62hf, the newest file. It has no server pack, so the window says the server is built from the pack's mod list, and it lists three mods to download from CurseForge's own site: Fixed Diagonal Walls, BMC "Datafixer" and Structory. Modpack mods to download from CurseForge covers that step. When this guide was checked, the install added 384 mods, turned off 72 that only run on players' computers, and the server started with Install without them ticked. To use the v62 server pack instead, pick BMC4 [FORGE] 1.20.1 v62 in the version dropdown. Tell your players to run the version the server has. Then press Start on the Console and wait for For help, type.

Settings

Neither server pack ships a server.properties, so the server starts with Minecraft's defaults. Open the Config Editor to set Player slots, Server list message and View distance (chunks), then restart. Minecraft server.properties explained covers every option.

Common problems

• A player cannot join. Check they run the same edition, Minecraft version and loader as the server.
• The server crashes at boot. Find and read a crash report shows how to name the mod at fault.
