World Preview NeoForged
This is an unofficial port of the World Preview. The original mod did support 1.21.x but its only in fabric and forge modloaders. It was a vital mod for my use cases so I decided to port this incredibly versatile tool so the setup is easier especially when you are on the lookout for the perfect spawn.
IMPORTANT
However TFC does not have full compatibility with this port but World Preview TFC does.
