TinyBlocks is a subgrid engine that only works on NeoForge 1.21.1 for now. It adds an invisible grid inside a single block space, letting other mods place and interact with scaled-down blocks at any even subdivision — 1/2, 1/4, 1/8, 1/16, or beyond.
The engine provides:
- Subgrid blocks in any even grid size (8×8×8 and 16×16×16 included by default)
- Per-piece hitboxes, mining progress, crack animation, and particles
- A PieceDefinition API for registering custom pieces with rendering, hardness, tool requirements, drops, ticking, NBT persistence, and GUI interaction
- A TinyPieceItem base class for placement items
- Debug blocks you can get by doing /give @p tinyblocks:...
TinyBlocks ships no pieces or items of its own — it is a foundation for other mods to build on.
