Shaper – Support Tool for Voxel Shape Exporting

Shaper is a support API for modders to define, load, and export voxel shapes (hitboxes) efficiently.
You can either use the Blockbench integration (via the Shaper plugin) to export shapes directly, or write your own hitbox JSON files by hand. More details can be found in the wiki.
Shaper supports Fabric, Forge, and Quilt.
