Ok this is a new Feature added just for supporters of the mod.

It is a MiniPreview of the Current Pregeneration.

Which you will get access to by becoming a Supporter (Check main page)

This feature is basically Creating a MiniMap of the pregenerated area and displayed to you as glorified progressbar.

It also works in a multiplayer context. Its limit is 1k chunk radius anything outside of its radius won't be rendered. And if a area is black that means it didn't touch that area.

 

Changelog:

Version 3.3.0:

- Added: MiniMap Preview to the Mod that allows supporters to see what was pregenerated during pregeneration.
