Any way to regenerate part of my world ?

For some reason a huge area around spawn (inc spawn) has regenerated new chunks and now the world is corrupted with huge wall chunks missing around the area that was regenrated.
Any way to fix this? I need to have this whole area regen new chunks so that these huge walls of missing ground can be regend.

It looks like this now

Old problem. I still havent figured out why is this happening.... generate a map from MC and then move it to Bukkit or use voxelsniper or other world manipulating plugins to smoothen things up

 

Worldedit has a command to do that. I'm not sure how well it works though.

- install worldedit
- fly to bad chunk
- type //chunk
- type //regen
- boom, chunk regenerated

If it doesn't produce the correct result then it's the other chunk that is incorrect and needs to be regenerated...

 

If worldEdit doesn't fix it, it's likely an issue with your world's seed somehow getting changed. Not sure how/why, might be.

 

The seed will be recreated if the current seed is corrupt/missing, So just keep a backup of the world and/or seed.

 

Ah, that explains.

 

Even if you keep the same seed, every minecraft update to the biomes will change the world generation and it's impossible to have land that matches.

 

Always good to learn new stuff
