Jurassic World Reborn II modpack Minecraft server

Jurassic World Reborn II is a dinosaur modpack for Minecraft 1.20.1 on Forge. Its CurseForge page describes extracting DNA from fossils, raising prehistoric creatures and building a park, alongside tech and magic mods and extra dimensions. You install the server from the Modpacks tab, using the pack's CurseForge server pack.

Checked against Jurassic World Reborn II v1.1.7 (the CurseForge file dated 20 October 2026) on Forge 47.4.28 and Minecraft 1.20.1, October 2026.

What the pack needs

• Minecraft 1.20.1 with Forge 47.4.28. The server pack's variables.txt names both. Java 17 runs Minecraft 1.20.1, and the panel selects it.
• A lot of memory. The author's page lists a minimum of 14 GB of RAM for a server and recommends 16 GB, and the mods folder holds 502 jars. The pack's start scripts ask for 8 GB, but the panel sizes the heap from your plan's RAM, so how much RAM a Minecraft server needs matters before you pick a plan.
• Disk space. The server pack downloads at about 1.3 GB and unpacks to about 1.4 GB, and the install needs room for both.
• Players. They install Jurassic World Reborn II v1.1.7 from the CurseForge app. The author's page says OptiFine is incompatible with the pack.

Install the server

On the CurseForge chip in Modpacks, search for Jurassic World Reborn II and pick Jurassic World Reborn II. Two similar projects are different packs: Jurassic World Reborn (no II) and Jurassic World Reborn 2 LITE. The popup names Forge and Minecraft 1.20.1. The rest of the window (the backup, the EULA and holding the install button) is in Install a CurseForge modpack.

The pack ships no Forge files of its own, so the install reads variables.txt and sets up Forge 47.4.28 itself. Then press Start on the Console and wait for For help, type.

Settings the pack ships

The install keeps the server.properties that comes in the server pack. It sets allow-flight=true, max-tick-time=180000, view-distance=6 and simulation-distance=5. In Config Editor these are Allow flight, Watchdog timeout (ms), View distance (chunks) and Simulation distance (chunks). Raise the distances only if the RAM card on the Console tab and the TPS reading in the left rail stay healthy.

Common problems

• A player is refused. They need v1.1.7 on Minecraft 1.20.1 with Forge. If that matches, compare their mod list with the server's mods folder.
• The server runs out of memory or lags. Watch the RAM card on the Console tab and the TPS reading in the left rail. If the RAM card stays full, the author's 14 GB minimum is the figure to compare against. Why is my server lagging has more. If it still crashes at boot, the crash report names the mod: find and read a crash report.
