Strange behavior when rendering below zero

[Dmistass]

I'm the team leader for BTE Balkans and TeamCIS in BuildTheEarth project, and we're having a problem: we're using world offsets to fit everything within the datapack's 4064-block-height limit for world expansion. But BlueMap displays everything below zero with errors.

It starts displaying without errors only when zoomed in.

What you are experiencing is a combination of multiple known issues the webapp has with displaying negative y areas or high positive y areas (>1000). These issues are unfortunately quite embedded into the functionality of the webapp, so there is no "easy fix" for them that one could implement.

I am currently working on a full webapp-rewrite, and this is one of the things i want to fix with that.
Unfortunately there won't be a quick solution for you in the meantime.

I see, okay. We will wait for fix. Good luck!
