I’m working on a project called Obsidian Sonic Spire. I chose Base-44 for the coordinate system to keep the database light while scaling to millions of blocks.

The logic: Newcomers stack at the bottom, pushing the 'Peak' higher into the atmosphere.

I’m struggling with the transition between the 'Earth' environment and 'Space' as the Y-axis increases. Does anyone have experience with dynamic skybox blending in Three.js?
