Precision Lignumis

An addon mod for the Lignumis planet (Space Age). It adds a third science pack, a real rocket silo with automated cargo shipping, a composite-materials chain, and wood treatment — and folds in several previously separate add-ons (wood pyrolysis, gold ammo, precision module, steam car) as built-in, first-party content.

⚠ Alpha status — active development.
This mod is not finished and is still being iterated on. Recipes, technologies, entity stats, and even prototype names can change between versions without a proper migration path. There is no guarantee that a save that works today will keep working after an update — a future version could break existing factories built around this mod's content. Play on a separate save you don't mind losing, and keep backups if you're invested in a playthrough.

Pyrolysis chain

New recipe category turns wood or peat into biochar (a solid fuel/reagent) and pyrolysis oil (a fluid), processed in the desiccation furnace.
Pyrolysis Science Pack — the mod's third science pack, crafted from biochar, pyrolysis oil, and gold plate. Depending on a Lignumis setting, it may have a "hot" variant that spoils back into the regular pack over time.
Treated Lumber — wood processed with pyrolysis oil, used throughout the mod's higher-tier recipes. Optional upgrade recipes let you craft treated versions of wooden walls and (if enabled in mod settings) faster transport belts.

Metallurgy and materials

Coke from biochar — an additional smelting recipe for the kiln, feeding into gold/alloy metallurgy.
Low-Density Structure (Wood) — a wood/biochar-based alternative crafted through liquor distillation, used as a structural material for higher-tier builds (rocket parts, precision module).

Combat

Gold Darts Magazine — an upgraded dart ammo that slows hit targets, craftable from wood darts and gold plate, with a cheaper pyrolysis-tier (biochar/coke) variant once its technology is researched.
Precision Module — a tier-1 quality module (speed penalty, quality bonus) built from gold plate, biochar, treated lumber, and a gold stromatolite seed. Also unlocks a seed-propagation recipe for renewable stromatolite seeds.

Steam Car (under change for the next version)

A vehicle built on Lignumis: a 30-slot trunk, and a 4×2 equipment grid.
Runs on Compressed Steam Canisters (craftable from gold plate and steam, or a cheaper biochar variant).
Unarmed by design — it's a transport/logistics vehicle, not a combat vehicle.

Rocket silo and automated cargo shipping

Precision Rocket Silo — a genuine rocket silo (not the early-escape shortcut silo), built from gold plate, treated lumber, stone brick, and biochar.
The silo auto-generates a small loading terminal next to it; fill it (by hand or inserters) and the silo will launch automatically once it's full or has reached its weight cap — no manual "launch" click needed.
Launched cargo is queued and, after a short delay, delivered to a target planet (Nauvis by default) as a falling pod, landing at a Precision Cargo Terminal — a real active-provider logistics chest that integrates with existing bot networks. Overflow that doesn't fit spills on the ground instead of being lost.
A small status panel on the silo's GUI shows current load and a shortcut button to open the loading terminal directly.

It also adds circuit-network connectors to a few Lignumis entities (basic radar, wood lab, wood splitter, burner lamp), and includes compatibility hooks for the alloy-smelting, Wood-Walls, and crushing-industry mods where present.

Once more: this is an alpha build under active development. Expect balance changes, renamed prototypes, and possible breaking changes between versions. Recommended for a dedicated test save rather than a main long-term factory.
