NeoOrigins Content Config Reference

Server-controlled content toggles live in the TOML file config/neoorigins/content.toml. Unlike client.toml (per-player), this is a SERVER config: NeoForge auto-syncs it to every connecting client, so whatever the server decides is what every player sees. Disabling an origin here genuinely hides it from remote clients’ selection screens: the server is the single source of truth.

The file is created with defaults on first launch. Edit it while the game/server is closed. Resolution follows standard NeoForge server-config rules:

• config/neoorigins/content.toml: the global default for this install.
• <world>/serverconfig/neoorigins/content.toml: a per-world copy, if present, overrides the global file for that world.

These values are read only after a world is active, so they do not participate in the boot-time datapack reload.

Config split (2.2.2). content.toml is one of four config files, and the only true SERVER config among them: its siblings gameplay.toml, admin.toml and power_overrides.toml are COMMON configs (loaded early, not synced to clients, no per-world copy). This doc covers content.toml only.

Global toggles

These three live at the top of the file, outside any section.

Option	Type	Default	Description
disable_resource_bars	bool	false	Hide all resource bars (mana, stamina, rage, etc.) from the HUD globally. Any active power that would normally cost a resource instead falls back to costing hunger: resource_cost_amount food points are deducted. Useful for packs that prefer vanilla hunger as the universal ability cost.
disable_night_vision	bool	false	Suppress the minecraft:night_vision effect globally. Any power that would apply it (the neoorigins:night_vision / persistent_effect path) no longer brightens the screen. Only night vision is stripped; other effects on the same power still apply. For packs that want darkness to stay threatening.
disable_enhanced_vision	bool	false	Withhold the neoorigins:enhanced_vision capability globally. The client-side low-light brightness boost (cat eyes, salamander, oculus drone, etc.) never turns on because the capability is never sent to clients. Independent of disable_night_vision: these are two separate mechanisms and can be toggled separately.

The two vision toggles are intentionally separate: disable_night_vision targets the vanilla potion-effect brightening, while disable_enhanced_vision targets NeoOrigins’ own brightness-curve capability. Turn off one, both, or neither.

Both outrank the player-facing Toggle Night Vision keybind. That key is a personal preference switch and only ever turns night vision off on top of what the server already permits: on a server with disable_night_vision = true, pressing it reports that night vision is disabled and changes nothing. See the player toggle section for the player-side half.

[origins]: per-origin enable toggles

The built-in origins each have a boolean here, defaulting to true. Set one to false to hide that origin from the selection screen.

Behaviour	Detail
Key	The origin’s path id (e.g. merling, automaton, stoneguard).
Keys generated	human, merling, avian, blazeling, elytrian, enderian, arachnid, shulk, phantom, feline, golem, caveborn, sylvan, draconic, revenant, tiny, abyssal, voidwalker, stoneguard, verdant, umbral, inchling, sporeling, frostborn, strider, siren, piglin, hiveling, cinderborn, sculkborn, enderite, necromancer, gorgon, automaton, kraken, warden, dwarf, breeze, vampire, air_mage, darkness_mage, earth_mage, fire_mage, gravity_mage, water_mage, monster_tamer, skeleton, slime, wraith, asura, windwalker, qi_cultivator, golden_body, iron_monk, sword_immortal (55 keys). The Dragon Survival origins (cave_dragon, forest_dragon, sea_dragon) have no toggle here.
Default	true (enabled).
When disabled	Hidden from the selection screen, but still assignable via /neoorigins set <player> neoorigins:<id>. The origin stays registered.
Scope	Matched by id: a toggle applies to neoorigins:<key> only. Origins in any other namespace, whether from datapacks or originpacks/, are not affected by these toggles.

[origins]
    human = true
    merling = true
    automaton = false   # hidden from the picker, still /set-able

[classes]: per-class enable toggles

The same mechanism for the built-in classes (class_warrior, class_archer, class_cleric, …), each defaulting to true.

Behaviour	Detail
Key	The class’s path id (e.g. class_warrior).
Keys generated	class_warrior, class_archer, class_miner, class_beastmaster, class_explorer, class_sentinel, class_herbalist, class_scout, class_berserker, class_titan, class_rogue, class_lumberjack, class_blacksmith, class_cook, class_merchant, class_cleric, class_nitwit, class_fisher, class_mason, class_paladin (20 keys).
Default	true (enabled).
When disabled	Hidden from the class selection screen, the same way as a disabled origin: the class stays registered and is still assignable via /neoorigins set.
All disabled	If every class is set to false, the class selection screen is skipped entirely.

[classes]
    class_warrior = true
    class_nitwit = false
