hbmspace:roots
Flat root tunnels filled with a block.
Flat, thin tunnels that turn replaceable blocks into fill, or lava_fill at and below lava_level. Once a column passed a top block, a filler block above the cut becomes cover. On 26.3, a minecraft:noise generator whose biomes list a Space carver runs its carving after the surface pass, with vanilla carvers of the same biomes; Space carvers work only in such generators.
Fields
| Field | Meaning and default | Range |
|---|---|---|
probability | Chance that a source chunk starts the carver. | [0, 1] |
y | Vanilla height provider for start heights. | |
y_scale | Vanilla float provider: vertical scale of rooms. | |
lava_level | Vertical anchor at and below which cuts fill with the lava block. | |
replaceable | Block ID, #tag or ID list: blocks the carver may cut. | |
fill | Tunnel fill. | |
lava_fill | Fill at and below lava_level. | |
top | Block ID, #tag or ID list: surface blocks. | |
filler | Block ID, #tag or ID list: blocks covered when above a cut. | |

The top-level type selects this carver; the remaining fields belong beside it.
