All the Mods 11 modpack Minecraft server

All the Mods 11 (ATM11) is a NeoForge modpack from the ATMTeam for Minecraft 26.1.2. It is the newest numbered All the Mods pack and it is still in beta: the CurseForge page summary reads "Super early alpha for 26.1.2", and its newest files carry a beta version number. You install the server from the Modpacks tab, using the pack's own server files from CurseForge.

Checked against All the Mods 11 0.12.0-beta (the CurseForge file dated 15 October 2026) and its server files, on NeoForge 26.1.2.109 and Minecraft 26.1.2, October 2026.

What the pack needs

• Minecraft 26.1.2 with NeoForge 26.1.2.109. The pack's own start script names that NeoForge build, and says Minecraft 26.1.2 needs Java 25. The panel switches Java for you, and Java 25 is what it picks for a 26.x version.
• Memory. The CurseForge page gives no figure. The server files' user_jvm_args.txt asks for -Xms4G and -Xmx8G and calls 4 GB "a good default for a modded server", 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. The server files' mods folder holds 280 jar files.
• Disk space. The server files are a download of about 623 MB and unpack to about 736 MB. Both sit on your plan's disk while it unpacks, 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. This guide installs 0.12.0-beta. Players should run that version from the CurseForge app. A beta changes often, so expect to update the server and the players together.

Install the server files

Press the CurseForge chip above the search box and search for All the Mods 11. Press Install on All the Mods 11 - ATM11. The results also list other packs from the same team, such as All the Mods 10 and All the Mons, so check the number in the name. The popup names NeoForge and Minecraft 26.1.2, and the install runs the NeoForge installer that the pack ships. Everything else in the window (the version list, the backup and the EULA) is covered in Install a CurseForge modpack. Then press Start on the Console and wait for For help, type.

Settings to set yourself

The pack's start script writes a server.properties on a fresh server with allow-flight=true, motd=All the Mods 11, max-tick-time=180000, simulation-distance=5 and view-distance=8. The panel does not run that script and the server files carry no server.properties, so set these yourself in the Config Editor and restart:

• Allow flight under Gameplay.
• Watchdog timeout (ms) under Performance.
• Simulation distance (chunks) and View distance (chunks) under Performance.
• Server list message under World.

Common problems

• The install ends with "no server engine could be set up". The loader step did not finish. Copy what the Console printed during the install and send it to support with the pack name.
• Players stick when they touch a fluid. The 0.12.0-beta changelog says fluids from most mods freeze player movement when touched and that this should be reported to those mods, not to ATM.
• Quests look unfinished. The same changelog says the quests added are work in progress and placeholders.
