Description

The builds people make in GT New Horizons have made all of us dream. A lot of that comes from blocks that never made it to newer versions, so I ported them to Forge 1.20.1. It started with ArchitectureCraft and grew from there.

Architecture

Put almost any block in the Sawbench and cut it into one of over 100 shapes: roofs, slopes, slope tiles, cylinders, spheres, arches, columns, cornices, balustrades and more. All the models come from the GTNH version.

Roofs join on their own, so ridges, valleys and hip roofs just work. Placement behaves like in GTNH on floors, ceilings and walls, and sneaking lets you put a shape flat against a wall.

You also get the usual tools:

  • Hammer to rotate shapes
  • Chisel to break or restore roof connections
  • Cladding to cover sloped faces with a second material

Every shape also has a glowing version.

Decoration

  • 16 Chroma Lamps with neon textures, all at light level 15
  • 16 tinted glass blocks
  • LabPBR textures included, so lamps glow and glass looks right with shaders

Compatibility

  • CB Microblocks: lamps and glass can be cut into microblocks, no config needed
  • FramedBlocks, Effortless Building and Building Gadgets 2
  • Works with or without shaders, in singleplayer and on servers
  • Recipes are plain vanilla, so pack makers can swap them with KubeJS or a datapack

You're welcome to use it in any modpack.

Credits

This mod wouldn't exist without:

  • gcewing for the original ArchitectureCraft, and TridentMC for the 1.12+ ports and the 1.21 rewrite
  • The GT New Horizons team for the shape models, roof geometry and placement rules
  • OneEyeMaker for the Ztones-Unofficial glass textures, based on Ztones by riciJak

Disclaimer

The architecture module started from TridentMC's 1.21 ArchitectureCraft rewrite. AI-assisted coding was used to clean up that code, bring it to Forge 1.20.1 and implement the compatibility. The optimisation work, all features and how they behave (placement, roofs, tools, shading, decoration blocks, recipes) were done by me, tested in game and reworked until they matched the GTNH version. Source code on GitHub.

Feedback

Bug reports, ideas and the roadmap are on the Discord. The source code is on GitHub.
