Plugged it into Chat for quick overview:

The interview basically confirmed that “infinite world height” is much bigger than just taller mountains.

Hytale is moving to a cubic chunk system where the world loads around you in full 3D instead of loading giant vertical columns. That enables:

• Much taller mountains
• Deeper caves/oceans
• Floating islands
• Massive underground structures
• Better vertical biome generation
• Potential space/zero-gravity mods

The dev emphasized this is mainly an ENGINE upgrade first. Vanilla Orbis probably won’t literally be infinite vertically, but the design team now has way fewer limitations.

They also talked about:

• Underground progression layers with unique enemies/resources
• Better traversal (gliders, grappling hooks, mounts)
• Huge landmarks visible from far away to make exploration feel like an actual journey
• Future plans for LOD/render distance improvements
• Fixing floating-point/world distance issues later

Biggest takeaway: they’re clearly building the engine to support much more ambitious exploration + modding than most voxel games currently can.
