UNITY IMPORT

Drop the source tilesheet PNG into Assets, set Sprite Mode = Multiple, and slice via the Sprite Editor at the JSON tileSize (7 columns × 7 rows for the full 47-blob set, 2 trailing empties at the end). Set pixels-per-unit to match (32 pixels-per-unit for a 32² tileset is a sensible default).

Create a RuleTile asset; for each tile in the JSON, add a rule with the sprite at its (col, row) cell and neighbour flags from the neighbours object. The ZIP bundle ships a script that auto-builds the RuleTile from the JSON if you want to skip the manual step.

Voxel exports — GLB: drag the .glb into Assets and Unity imports it as a model prefab with per-color materials baked in; URP/Lit or Standard works out of the box. OBJ: unzip voxel-model.zip into a single folder under Assets — Unity follows the mtllib reference and binds the palette PNG via map_Kd automatically, so URP Lit shows your colors with no manual material setup. Multi-frame projects emit one .obj per frame against per-frame palettes (no cross-frame colour blending).
