Corners
by stohun
Corners adds 1/8th-volume corner blocks for vanilla-style builds, with multipart models that make more detailed shapes possible.
What it does
Corners places one-eighth-volume corner blocks in the world, built on the multipart blockstate system. A placed corner keeps its configuration, and corners of different materials do not mix within one placement. Internal face culling hides the faces that touch another corner, and the generated part structure supports rotation and mirroring.
Copper corners oxidise and can be waxed, matching the behaviour of copper blocks in vanilla. Wooden corners burn as fuel, and five corners smelt one item. The textures are the vanilla ones, so most resource packs apply to them without changes.
Installation requires Fabric API. Servers that run it need every player to install it too. Files are published for Fabric alone, for game version 1.21.1, under the CC0 1.0 Universal license, which places the code in the public domain, and the source code and issue tracker are public.
Key features
Eighth-volume corner blocks
Each corner fills one eighth of a full block, allowing finer shapes than slabs or stairs alone.
Multipart corner models
Corners are built from multipart blockstate parts, so a single placed block can combine several cut faces.
Copper corner oxidation
Copper corners oxidise over time and can be waxed to stop the change, like other copper blocks.
Wooden corners as fuel
Wooden corners burn in furnaces, and five corners smelt one item, so they can replace some wood use.
Rotation and mirroring
Generated corner structures support rotation and mirroring, which helps when building symmetric parts.

Who it’s for: Builders who want finer decorative shapes, and players who use resource packs that keep vanilla textures.
