A modpack turned into a whole lab.

FBZ Lab is my public workshop. P.R.I.S.M. lives here, along with the world behind it and the tools I ended up building because I needed them myself.

Changelog

What changed, without the commit soup.

world networkDevelopment update

WGL and WorldGen now read the same terrain data.

Added a shared terrain facade for the approved Echorys plan. The review tool and Minecraft materializer now consume the same source instead of inventing separate interpretations.

  • Shared approved terrain facade
  • One source for review and materialization
  • Separate interpretations removed

The continental layout is locked.

The macro composition for Echorys passed visual review and moved into an approved-plan workflow. Higher-fidelity terrain and materialization remain in development.

  • Macro composition approved
  • Plan moved into the reviewable workflow
  • Terrain materialization continues
