FAQ - Dark Matter Replicators Reborn

1. What exactly does this mod do?

It adds replicators that produce items using electricity only. It dynamically generates replication recipes for almost any item (including those from compatible mods) and introduces specialized labs to research each replication technology individually.

2. Where does Tenemut ore spawn?

It depends on your startup settings: * Without Space Age: It spawns on Nauvis, similar to uranium. * With Space Age: By default, it spawns on Nauvis to allow seamless early-game progression. However, you can change its primary spawning planet (to Vulcanus, Fulgora, Gleba, or Aquilo) and choose whether to spawn it on other planets in the startup settings.

3. How is the energy cost of replication calculated?

The mod dynamically calculates costs based on the item's recipe ingredients. You can choose between two methods in the startup settings: * Raw Ingredients (Flat): Sums the base cost of all raw ingredients. * Recursive Steps (Compounding): Multiplies the cost cumulatively based on the manufacturing steps. * Note: The crafting time scales proportionally to the calculated resource cost to balance energy draw.

4. Can I replicate fluids or replicate items in space?

By default, replicating items on space platforms is disabled, but you can enable it via the "Replication in space" startup setting. Replicated fluids are delivered in configurable batches (25 units by default).

5. How can I make my own mod compatible with DMR?

The mod exposes helper functions like repltech_recipe, repltech_item, and repltech_ore (see lib/repltech.lua in the mod source). DMR auto-generates replication for items your recipes produce once they are unlocked by any researchable technology — no per-mod list is needed; use the data-final-fixes stage so DMR sees your recipes.

6. Where should I report bugs or compatibility issues?

If you encounter a bug, startup crash, or mod compatibility issue, please post it on our GitHub Issues Tracker or under the Discussions tab on the Factorio Mod Portal. When reporting, please include any error messages, your startup logs, and a list of other active mods to help us identify and resolve the issue quickly.

7. Can I play without tenemut ore? How do I get tenemut from electricity?

Yes. A new startup setting called Tenemut source has three modes: * Ore patches (default): today's behaviour — tenemut ore generates in the world and there is no synthesizer machine. * Ore patches + synthesis: tenemut ore still generates, and the Dark Matter Synthesizer is also available. * Synthesis only: no tenemut ore is placed on any planet — the Dark Matter Synthesizer becomes the only way to obtain tenemut.

In the two modes that include synthesis, the Dark Matter Synthesizer is unlocked early by a technology that requires automation science packs only. It consumes no items at all — only electricity: 1 MW of continuous power, 4 seconds per tenemut. Because the recipe is energy-only, it deliberately never accepts productivity modules, so a steady 1 MW grid feed is all you need.

This setting only affects new worlds: an existing save keeps the tenemut patches already on its map, so switching to "Synthesis only" never removes ore you already have.
