How do I access the BlueMap after installing it?

Once installed and your world/server is running, open a web browser and go to localhost:8100 (or whatever port is set in your config). You should see your 3D map loaded and ready to explore.

Does BlueMap work on multiplayer servers?

Yes. Drop the mod into your server's mods folder and restart. Players can access the map through a browser using your server's IP address and the BlueMap port. Perfect for letting players see the map without needing the mod installed.

Does BlueMap slow down my server?

It depends on your world size and server power. The initial map generation takes time and resources, but once generated, updates are fairly lightweight. You can adjust settings to render maps less frequently if you need to conserve resources.

Can I customize how my map looks?

Yes. BlueMap has config files where you can change colors, transparency, which biomes display, marker icons, and more. You can even set up multiple maps for different worlds or views.

Which Minecraft versions does BlueMap support?

BlueMap has versions for 1.14.4 all the way up to 1.21.3. Older versions work on Forge only, while newer versions support Forge, Fabric, and NeoForge. Check the downloads section for your specific version.

BlueMap Mod (1.21.3, 1.20.1) - 3D World Mapper

BlueMap is a Minecraft mod that creates 3D maps of your world. Instead of installing a premade map, you point it at your own world files and it generates an interactive map you can view in your web browser. It’s useful for checking out the big picture of your builds, running a world tour for friends, or just seeing what your terrain looks like from above.

What BlueMap Does

BlueMap reads your world data and renders it as a 3D model. You can zoom in and out, rotate the view, and explore your world from angles you can’t normally get in-game. It works on single-player worlds and multiplayer servers. The map updates automatically or on demand, depending on your settings.

Features

3D World Rendering – See your entire world from above and at any angle.
Web-Based Viewer – Access maps through a browser on any device. No special launcher or viewer needed.
Live Updates – Configure the map to update automatically as you build, or refresh it manually.
Server Compatible – Works on both single-player worlds and multiplayer servers.
Custom Styling – Customize colors, markers, and how the map looks.

What You Need

BlueMap requires one of these mod loaders:

How to Install

Once you’ve got Forge, Fabric, or NeoForge set up:

Download the BlueMap jar for your version and loader.
Drop it in your mods folder (`.minecraft/mods` for single-player, or your server’s mods folder).
Launch the game or restart your server.
Open your browser and navigate to `localhost:8100` to view your map (the port may differ based on your config).
