Uninstalling Iris issue

[Pen92he]

Problem

I encountered and #1163 the same question，I tried to fix it using world height fixzip, but my height doesn't match，Just like the log I uploaded, there will still be warnings. Can you create a suitable world height fixzip for me?

If you need me to provide the egion file and the level.dat, please contact me

if it's only height map or lighting it's fine

@Pen92he if you send me your full log I can give you a plugin that will fix it in the long run

kk gonna get back to you in a few minutes

[CrazyDev05]

you can use this, it loads all generated chunks once with a code modification to prevent any unnecessary data loss
but it will still delete all blocks outside of the new world height

https://github.com/CrazyDev05/ChunkFixer/releases/tag/1.0.0-1.21.10
to start the process just run /chunkfixer
after the process is done you should delete the plugin

[CrazyDev05]

I also should point out that if you still have worlds that were generated by Iris there will be other issues like empty loot chests, no mobs spawning in custom biomes and structures or if you fully delete the Iris datapack broken biome colors

Thank you, may I ask if this will cause damage or lost to the chunk?

[CrazyDev05]

yes decreasing the world height is inherently destructive but if no one built above the normal height you should be able to notice it (all it would be deleting is air)
