Amulet-Map-Editor VS BedrockConnect

Edit: AmuletEditor: https://www.amuletmc.com/ Plugin to edit NBT: https://github.com/PREMIEREHELL/Amulet-Plugins/blob/main/EntitiePlugin_nbt_edit.py

There were a few projects that continued working on it. One of them, “MCEdit: Unified”, was supported until 2019, but I don’t believe it supported the MC 1.13 Block ID formats. The team remade it for newer versions and named it Amulet for MC 1.12+.

You can use Amulet to delete chunks that you don't want, and it seems to work with both Java and Bedrock worlds.

Try exporting your map then using Chunker to convert to .mcworld. If your world size is too big for it, try Amulet Editor. instead.

Use a map editor like Amulet to delete unused chunks of the map.

I’m not too experienced with it, but you can try to use amulet to try and edit the nether chunks

https://www.amuletmc.com It's pretty easy to use and it does offer the option to change biomes for selected chunks, as well as trim worlds etc.

If you have that, you can use Amulet to copy the chunks to a new world. Amulet also offers a feature that might be a better option for you. It will let you select chunks to save, then delete all others. This lets them regenerate with the new features included.

MCEdit is not compatible with worlds newer than 1.12.2. Some of the developers moved on to Amulet, though I'm not sure how feature complete it is.

There are a few other troubleshooting tips listed here that could help if you're still having an issue.

As a quick option for instant access you could follow this workaround which is helpful to have https://github.com/Pugmatt/BedrockConnect then added the server this way.

The negatives to self host or third party is that xbox/switch/PS users will need to use a loophole redirect service in order to play, but for our group of players, its been worth it. https://github.com/Pugmatt/BedrockConnect

They'll need to use a service like bedrock connect but yes it is 100% possible and i've done the exact same thing in the past.

For the DNS, I recommend https://github.com/Pugmatt/BedrockConnect

Can't join custom servers on consoles (without a DNS hack)

On the Xboxen use Bedrock Connect (see How to Join a Bedrock Edition Server on Xbox/Switch, or if you're a tech geek, you can go right to the source at https://github.com/Pugmatt/BedrockConnect).
