Sibling-mod progression overlays
NeroAgriculture progresses on its own native gates and never needs another mod. Optionally, when a sibling mod is present, a higher tier can additionally require that mod's Neroland arc gate — giving modpacks a cross-mod "link" feel.
| Tier / gate | Also requires (arc gate) | Opener mod |
|---|---|---|
| Forgite / Refinement | industrial_power | Nerotech |
| Orbite / Synthesis | reached_orbit | Nerospace |
| Colonite / Transmutation | first_colony | NeroColonies |
| Voidite / Ascension | deep_space | Nerospace |
Config: progression.sibling_overlays
off(default) — only the native gates apply; overlays are opt-in.auto— an overlay applies only when the opener mod is loaded. A Core-only game is never gated by an arc gate nothing could open, so standalone play is never blocked.on— always require the arc gate (for packs that drive it by other means).
The overlay is layered onto every resource-tier check — machines, planting, growth, harvest, automation and towers — and is dormant-safe when the sibling is absent.
