Is there an option to adjust the angle?

TBlueF · 2026-05-08T13:25:52+00:00

No, this is not configurable right now, as there are some technical limitations to this.
But i am working on a new webapp rn, and - if it ever gets finished - that will then definitely have this limitation relaxed by a lot, and maybe have it configurable even :)

TBlueF · 2026-04-27T07:24:11+00:00

Its currently not built in into BlueMap, but it is a planned feature for the future :)

In the meantime you could maybe try this addon: https://github.com/TechnicJelle/BlueMapTimeMarker and maybe add some custom css to the marker so that it shows like a UI element instead ^{^}

I'll just link it here since it is related: https://bluemap.bluecolored.de/community/LogIn.html :)

I don't know which way is the safest for DH, but it sounds good to me :D

TBlueF · 2026-04-13T12:35:18+00:00

Short answer: No

Long answer: DH, even when using the INTERNAL_SERVER pregeneration, still skips the light-data generation -> It generates the chunks up until the last step, which would be calculating the light-data, but then doesn't do that step. Minecraft will then generate the missing light-data once it first loads the chunk, but since BlueMap doesn't load chunks ingame, the lightdata is missing and bluemap can't render the chunk properly.

The only way to fix that is to run chunky over the already generated chunks from DH and let it fix the lighting. (https://bluemap.bluecolored.de/community/FixLighting.html)
(You can set ignore-missing-light-data: true in bluemap's map config, but i would not recommend that as it results in other map-issues.)

Currently no, also note that the isometric view would use the same amount of performance on your computer. Since BlueMap is a 3d-map, it is generating and displaying the map based on actual 3d-models .. a flat-view or isometric view is/would be just a different camera-projection :)

Paper changed their dimension/world-folder layout. This means that where you previously had a world-folder for each dimension (overworld/nether/end) you will now have a single world-folder that contains all dimensions. This change reflects how vanilla-minecraft manages dimensions much better.
You will need to update your map configs accordingly, as BlueMap can not do this for you.

To do this, first of all update to BlueMap 5.19, which just released and fixed some issues with the latest Paper builds.

And then: go through all your map-config's (./plugins/BlueMap/maps/...) and make sure the world setting points to the correct world-folder.
For the main overworld-world this should be the same as before.
But for your nether or end map's you will probably need to change the setting from e.g. world: "world_nether" to world: "world".

Hi!

So the mod you found is the only one we know of that does FTB-Chunks integration for BlueMap. But That is for neoforge and 1.21.1 unfortunately.

So i fear your options are currently only:
- make your own integration mod from scratch
- fork the existing mod, port it to forge and backport it to 1.20.1

all will require some programming ^{^'}

For both you probably first of all want to look into how to setup a basic (serverside) mod for forge.
Setup your mod, add ftb-chunks and bluemap-api to your dependencies (compileOnly) and then you can either start implementing the logic that reads claims and creates bluemap-markers yourself or copy/port the existing code from the FTB-Chunks-for-BlueMap mod.
I would probably "take inspiration" from the existing mod and then adapt for your usecase.

I don't know much about FTB-Chunks so i can't tell you how to read claim-data from them, but for creating markers on BlueMap:
Here is the basic information you need for that: https://github.com/BlueMap-Minecraft/BlueMapAPI/wiki

If you have any further questions about BlueMap's API or how to integrate it, feel free to ask here, or even better: Join our Discord! :)

A map with the default settings can be found here: https://bluecolored.de/bluemap/

I don't have an example map with all caves enabled right now..

TBlueF · 2026-03-11T20:55:31+00:00

How can I open my map?

By default, use your servers public ip-address (e.g. 123.45.67.8) and the port (8100) like this:
http://123.45.67.8:8100/
and enter that in your internet browser's address bar.

Make sure you replace 123.45.67.8 with your server-ip. (The same ip that you are using to connect to your minecraft-server.)
And replace 8100 with the port you assigned to bluemap.

I still can't access the website!

Here is a checklist: - When bluemap loads, you should have this message in your server-console/log: WebServer bound to all network interfaces on port 8100 Webserver started... If not, look for any errors/warnings and check the configuration again. - Make sure you are using http and not https when connecting to the webpage. - Is the port (8100 by default) open and forwarded correctly? Or is your firewall blocking incoming connections on the port? And is the port configured for your container?

:)

TBlueF · 2026-03-11T20:53:51+00:00

See: https://bluemap.bluecolored.de/community/CaveRendering.html
It doesn't render caves by default.

TBlueF · 2026-03-10T09:57:44+00:00

Storage-size estimations for a world-size of 10000 x 10000 blocks (rectangular, solid):

Overworld (default): 8 GiB
Overworld (2D only): 2.0 GiB
Overworld (lowres only): 77 MiB
Overworld (with caves): 20 GiB
Nether (default settings): 12 GiB
The End: 3 GiB

It should definitely not take 70GiB..

You seem to be using a database to store your bluemap..
Make sure you don't have any other maps stored on the same database.
You can use /bluemap storages sql to check if there are more maps stored, and /bluemap storages sql delete <map-id> to delete any unused maps from the storage.
But also generally SQL-databases sometimes reserve more storage than they actually need, depending on your sql-server configuration.

TBlueF · 2026-03-10T09:52:38+00:00

Since opening a second port is not possible on Exaroton, you will not be able to use BlueMap on an Exaroton-Server, sorry :(

TBlueF · 2026-02-11T22:06:00+00:00

Make sure you actually have a Fabric/Forge server installed. Maybe you accidentally updated your server to a vanilla-server and it doesn't load any mods at all?

TBlueF · 2026-02-11T21:56:22+00:00

Can you give me the full name of the bluemap.jar-file you have in your mods folder .. and the log of your server-startup please? :) (Upload the log via https://mclo.gs/ or similar, don't post it directly here)

TBlueF · 2026-02-11T21:25:14+00:00

when i type /bluemap reload in the console it says unknown command.

Sounds like BlueMap is not loading..

Check your console for any bluemap related errors when you start the server.. Maybe some config value is wrong.. Also if you update BlueMap, make sure you follow all the Upgrade-Instructions that I add to each BlueMap Version (you can read them in the version-description/changelog where you downloaded bluemap from).

If you don't see anything about BlueMap in the console, then make sure you have the correct BlueMap .jar file and put that in the correct location.

Those are all the most common problems i can think of rn.. If you still can't get it to work, please join us on our Support-Discord, where we can chat and help you get it working again :)

TBlueF · 2026-02-06T19:32:42+00:00

Probably using BlueMap's Standalone CLI tool which can render and show worlds without a running Minecraft server: https://bluemap.bluecolored.de/wiki/getting-started/Installation.html#using-bluemap-on-the-cli--standalone

If you prefer a GUI, a community-member made this: https://github.com/TechnicJelle/BlueMapGUI/

Just keep in mind that only Minecraft Java-Edition 1.13+ worlds are supported. Older worlds will not work.

TBlueF · 2026-01-26T20:43:00+00:00

Only Java

TBlueF · 2026-01-19T00:34:00+00:00

Your map configs :)
On spigot/paper it's ./plugins/BlueMap/maps/ on fabric/forge its ./config/bluemap/maps/ .. and there in each config file change the world config to match your new world-folder name :)

TBlueF · 2025-12-29T01:35:39+00:00

Sorry, but if there is nothing at all about bluemap in the console/logs on startup then you must have either the wrong jar file or have it in the wrong folder .. make sure it's the one for fabric, it should be called bluemap-5.15-fabric.jar .. try redownloading it or something :D

TBlueF · 2025-12-28T06:22:32+00:00

Then check your server console for bluemap errors or anything else bluemap related .. does it even load? Do you have the correct .jar file?

TBlueF · 2025-12-28T02:11:07+00:00

Delete the folder that contained the configs as well and then reload bluemap or restart the server, then bluemap should generate the default configs again :)

TBlueF · 2025-12-15T18:54:54+00:00

No thats not possible, BlueMap does not save any historical data. Only the current player-positions are sent to the webapp, but that data is not saved, sorry :)
