The Problem

Hi Everyone,

we are an 8-year old survival Server and due to the leave / cleanup of players, we need to regenerate pieces of the world.

Before the 1.18 Update it was no problem, the regenerated world had the same old biome borders like the original one.

Now, after the 1.18 Update, we all know that biomes has changed a lot....

For an example see the attached screenshot. On the left side you see the Original world and on the right side the same place with //regen

We have implemented a workaround for us that looks like this:

• Generate a Original World in 1.17 with Seed from World
• Generate all Chunks with Chunky, so the whole world is fully generated
• Switch Server Version to 1.18.x
• Generate all new Chunks below 0 with Chunky
  -> Now you have a world with the old biomes but with the new negative Things in it. We named it "converted original world"

If we want to regenerate a piece of our world, we go the exact same coordinates in the converted original world and copy / paste the region and now you will see, there isn't any hard border in the bioms, its just the same ;)

A Solution

So from our perspective it would be a great feature if we can select a world with UUID in the WorldEdit Config for the regeneration command so the worldedit selection is cut from this world instead of regenerated instead of the regular function with the worldseed and temp world an new 1.18 biomes.

Do you guys think this would be possible ?

Kind regards
Cola

This sounds like you want the snapshots feature, not regen. Regen calls the game's generator, while the snapshots feature restores the selected area to a previously saved world.

If you have a world that a UUID can be used for, you have a world that can be used as a snapshot. I'm not exactly understanding what you mean sorry?

As far as i understand the snapshot, we must create a snapshot of the peace of world before it is changed by users, correct?

This is in our case not possible, because users can build outside of the region and this piece can never be reverted, because we dont have a snapshot at all.

It would be a thousand times easier if we can select an UUID World instead of the temp world.

Ok, i missunderstood the Snapshop Feature. My fault, excuse me.

For all others - this one was the solution:
