Raw Blame History

Lignumis

This mod extends the early game of Space Age by putting you on the moon "Lignumis" before you escape to Nauvis. It concentrates on wood and steam technologies, giving you some early game production chains for those resources.

The duration of the stay on Lignumis will be rather short. The impact of the later game will still be substantial. There are several mod settings to alter the experience after leaving Lignumis to make it match your personal taste.

Warning when adding to existing games: With the default settings, this mod will break a few things in your existing bases and space ships. Check out the settings to disable what you don't like.

Streamers featuring Lignumis

Planet perks

Early bots

Unlock early personal bots with steam science even before reaching Nauvis. Start with 10 construction bots and upgrade to up to 30 with the heavy armor unlocked with automation science.

There is even a setting to move personal bots to wood science and buff them a bit to get them basically at game start.

New belt tier: Wooden belts

This new low-fidelity tier of belts is incredibly cheap and can be used for those low throughput applications.

Exported buildings: Lumber mill and burner agricultural tower

These burner buildings help with wood production on other planets and the lumber mill grants a 50% productivity bonus for wood-based items.

Exported products: Processing units and low density structures

These items are especially cheap to craft on Lignumis and can be exported to other planets that could use the resources better for other things.

Alternative recipes

The Lignumis plastic recipe can be used on other planets just with wood and water. Bring some peat and gold stromatolite seeds for the starter culture. Improve it even more by using the biochamber once unlocked.

Nutrients from wood pulp can be used on all planets for easy nutrients production.

Increased astroids

Lignumis orbit has increased amounts of astroids that also have an even distribution. That makes it ideal to jumpstart new space ships and for production platforms.

Late game technology: Quality assembler

Craft selected machines and items with a quality bonus of 25% by providing a special gold quality catalyst.

Wood production

Sources of wood per planet.

Mod recommendations

The following mods can be a great addition for this mod:

Inserter Fuel Leech

While optional, the intended way is to use this mod for the burner phase as it improves the fueling experience of burner entities.

For UPS optimizations, you can disable this mod once the burner phase is over.

Alternatives: Burner Leech Fork, Burner Leech

Optional wood mods

Any Planet Start

Allows you to choose the planet that Lignumis orbits. You can continue on Vulcanus, Fulgora or Gleba after leaving Lignumis. Some modded planets add APS support as well (sometimes with a separate mod).

Diversitree

Planted trees will have more than one variant.

Hot metals

If you like the idea that metals need to cool down after being smolten in a furnace, Lignumis gold has support for hot metals.

Wooden Military

If you want more of it than Lignumis offers, add this mod. It adds ammo for shotguns and there are settings for rockets and artillery shells.

Wooden Industry

If you like go more into the charcoal direction. It has no overlap with Lignumis and starts to get relevant on Nauvis.

Crushing Industry with Crushing Industry - Productivity Research

Recommended with high science cost settings. It adds crushers and crushed ores to increase productivity. Lignumis adds crushed gold ore and a technology to unlock the crusher with wood and steam science packs.

AAI Loaders

A wooden loader is added when this mod is active. Also supports AAI Loaders, a sane rebalance.

AAI Industry

Add this for increased complexity in the early Nauvis game. It has no effect on Lignumis, but Lignumis changes a few recipes this mod adds.

Brevven's mods

For even more complexity after Lignumis. They currently don't change anything on Lignumis itself.

Problematic / incompatible mods

The combination of AAI Industry and Any planet start is currently not supported.
Alien Biomes: Lignumis won't have any trees. It's playable, but not as intended.
The rest of the Wooden Universe: I marked the ones incompatible that don't make sense to combine or that wouldn't add more that is not already included.

Add compatibility to your mod

Lignumis, by default, adds wood and steam science packs during data-updates.lua to all technologies that match certain criteria. First it looks at a whitelist of science packs. If a technology has any of those, it is considered a candidate for adding the science packs. Then a blacklist for science packs and specific technology names is applied.

Also, Lignumis adds wood and steam science packs during data-updates.lua to all labs' inputs. If your lab is special use the lab_blacklist described below.

These lists are made available in data.lua in a global table called Lignumis to add compatibility for other mods.

`science_pack_whitelist`

A technology having any of these science packs as ingredient will get wood and steam science packs added.

As wood science packs can't be imported before coming back to Lignumis, only advanced Nauvis science packs are added here and exceptions are needed for advanced technologies that are required to upgrade Lignumis to export science packs.

`science_pack_blacklist`

A technology is skipped if it has any of these as ingredient.

If you have a planet that only uses its own science packs and must not rely on other science packs to be imported, add your science packs to the blacklist.

`science_blacklist`

These technologies are skipped even if they are matches according to above lists.

Use this list if you want to have wood and steam science packs added to most of your technologies, but skip some. Lignumis uses this list for technologies that match the whitelist but are required for coming back to Lignumis in order to create the science pack export.

As an alternative, you can add lignumis_skip_science_packs = true to any technology.

`lab_blacklist`

Don't touch inputs for labs in this list.

Lignumis adds wood and steam science packs to all labs' inputs in data-updates.lua so modded labs will support them. If your modded lab is special and it should not support these science packs, use this list or set the inputs in data-final-fixes.lua.

Chaning the second planet (a.k.a. transition to Nauvis)

If you want to create a mod that moves Lignumis to another planet, there is a hidden setting for the scripted transition to teleport the player not to Nauvis but to any planet you like. This doesn't change any technologies or the location of Lignumis on the map. Make sure you adjust the prototypes as well on your end.

In settings-updates.lua add the following to switch to Gleba as the second planet:

data.raw["string-setting"]["lignumis-second-planet"].allowed_values = { "gleba" }
data.raw["string-setting"]["lignumis-second-planet"].default_value = "gleba"
