Rooted Dirt

All slabs have proper recipes and appear in the Building Blocks creative tab.

World Generation

Terrain slabs generate naturally at terrain edges, creating smoother transitions between elevations. Works with:

All dirt-type slabs
Stone variants (stone, deepslate, tuff, andesite, diorite, granite)
Sandstone variants

Plants on bottom slabs automatically convert to offset-rendered slab variants.

Plants render correctly on bottom slabs with proper vertical offset. Supported plants:

Crops: Wheat, Carrots, Potatoes, Beetroots, Torchflower, Pitcher Plant

Flowers: Dandelion, Poppy, Blue Orchid, Allium, Azure Bluet, Tulips (all colors), Oxeye Daisy, Cornflower, Lily of the Valley, Wither Rose, Torchflower, Eyeblossoms

Saplings: All vanilla saplings (Oak, Spruce, Birch, Jungle, Acacia, Dark Oak, Cherry, Mangrove, Pale Oak)

Snow Support

Snow layers work properly on bottom slabs:

Accumulates from weather in snowy biomes
Snow golems leave trails on slabs
Manual placement with snow items
Grass and mycelium slabs show snowy texture when snow is on top

Tool Interactions

Shovel:

Right-click dirt slab → Path slab
Sneak + right-click full block or double slab → Single slab
Sneak + right-click single slab → Toggle top/bottom placement

Hoe:

Right-click coarse dirt slab → Dirt slab
Right-click dirt/path slab → Farmland slab
Right-click farmland → Dirt slab

Vanilla Parity

Grass, podzol, and mycelium spread across blocks and slabs
Sheep eat grass from grass slabs
Bonemeal fertilizes grass slabs
Giant pines convert adjacent dirt/grass slabs to podzol
Farmland slabs support crop growth
Melons/pumpkins grow onto appropriate slab types
Villager farmers interact with farmland slabs
All appropriate particles and sounds
