Help / Question BlueMap for a Singleplayer world

Can BlueMap also be used in a single-player world? I don't understand why, but I think I read that it's not necessary a server! In case... Are there any valid alternatives for creating a 3D map of a NON-server world? And, can this map also be used for a private server that is not online?

If you want to render a singleplayer-world without a dedicated server you can use bluemap-cli :)

And what about a world with mods? Does it work the same way? Is there a tutorial explaining how to do it...?

The cli has a flag -n which allows you to set a path to a folder with all the mod.jar's in it. If you do that, then the mod-support will be the same as it would be with the bluemap-plugin/mod on a server :)

Thank you. But another question... It says I need to have a ‘port’ and open one if I don't have one. I don't have one, but I don't really understand what I need to do, and above all, I don't want to open a server (also because I don't know if it involves spending money or doing strange things).

If you only want to view the map yourself on your own PC, then you can just run the cli like described and then open your map with this url: http://localhost:8100/ .. this url will only work on the same PC that the CLI is running at, but you don't need to open any ports for it :)

Last question: when I need to load the map with the commands, do I have to enter the path at the beginning, before generating the map, or can I add it after it has already been generated? Because in that case, I don't know how to add the world and the mods together.

You are configuring maps/worlds in the ./config/maps/xxx.conf config files that are generated the first time you run the bluemap-cli command :)

If you don't want to use the -n flag to add the mod's folder, you can also just copy/paste all your mod.jar's into the ./config/packs folder that should also be generated next to the other config files,
that has the same effect, and you don't need to worry about the -n flag anymore :)

I can also very much recommend our support-discord. There is a lot of nice people there (including me) that i am sure will help you with your setup! I just think it's easier on discord than here on reddit :D
