# Space settings

Travel, worldgen, mobs, fluid reserves, radiation and machines.

Registry: `hbmspace:space_config`. Files: `data/hbmspace/hbmspace/space_config/<group>.json`. The settings load when the world opens and sync to joining clients; `/reload` leaves them unchanged. A higher-priority file replaces the whole group, and an omitted key uses its code default, which equals the shipped value. A missing group, an undeclared group or key, or an invalid value stops the world from loading.

## travel

| Field | Meaning and default | Range |
| - | - | - |
| `allow_nether_portals` | Accepted for compatibility; it has no effect. Default `false`. | |
| `max_probe_distance` | Half-width `R`: a player leaving their station cell is teleported to the orbited body at X and Z uniform in `[-R, R)`, Y 800. A Hard Drive without a survey centre rolls one in the same range. Default `32000`. | `[1, 1073741823]` |
| `max_station_distance` | A new orbital station takes a random cell within $\pm n$ per axis, $n = \mathrm{value}/1024$. Default `32000`. | `[1024, i32::MAX]` |
| `combat_pod_despawn` | `true` removes a combat drop pod block on its scheduled tick. Default `false`. | |

```json
{"allow_nether_portals": false, "combat_pod_despawn": false, "max_probe_distance": 32000, "max_station_distance": 32000}
```

## worldgen

| Field | Meaning and default |
| - | - |
| `enable_volcano_gen` | `false` omits the active vent block at the top of [`hbmspace:volcano`](https://movblock.mov/ntm-next/wiki/space/world-generation/volcano.md) cones; the cones still generate. Default `true`. |

```json
{"enable_volcano_gen": true}
```

## mobs

| Field | Meaning and default |
| - | - |
| `enable_mun_cows` | `false` stops Mun Cows spawning in the Mun biome. Default `true`. |
| `server_safety` | NTM's Quackos ignores kills. `true` counts each kill as 2, minus 1 per tick, and removes the entity once the count exceeds 20, so rapid repeated kills remove it. Default `false`. |

```json
{"enable_mun_cows": true, "server_safety": false}
```

## reserves

Fluid amounts of celestial oil, gas and brine deposits, read by NTM's oil drills. The [pumpjack's](https://movblock.mov/ntm-next/wiki/machine-settings/pumpjack.md) reserve multipliers apply on top. NTM's oil and bedrock oil deposits use the `earth_*` and `bedrock_*` values while Space is installed.
