About OCs Alternative Science Production
From Factorio Mod PortalThis mod adds the alternative science pack production with research and optional productivity techs. Did you ever wanted to cast military science packs? Now you can! Profit from the built-in productivity of the non-Nauvis buildings for your science production.
Alternative Recipes in two different modi
- The Foundry can craft automatic, logistics and military science packs. The recipes break the science packs down to molten metal and/or lava.
- The Biochamber can craft chemical and space science packs. The recipes are basically just the same as vanilla.
- The Electromagnetic Plant can craft utility and production science packs. Here, the biggest different can be seen as more intermediate crafting steps are included.
- The Cryogenic Plant does not get new recipes, but fits well within. It can still profit from the optional productivity researches.
Classic Mode
These are the seven[1] recipes I've created myself. They are tailored for my desire and have some variety of complexity. Overall, the material cost are always the same to the original recipe. [1]: with the mod [OCs Lava Casting], an additional alt recipes for military science with lava is added.
Experimental Mode
A more dynamic way of the recipes which should be compatible to most other mod changes. These are influenced by the settings of my core mod [OCs base assets]. They tend to have even more variety of complexity as they break down to the most basic materials like metal plates and plastic bars, while still keeping the overall raw material cost the same. The upside is that these will compatible to mostly any mod you throw at it, while the downside is that they tend to be less useful. But who am I to tell you what mode to choose?
Note: Both modes are exclusive via a mod setting, so choose before you use them widely.
Eight New Technologies
Each of these three groups has a special crafting bonus technology. For balance, the two late-game science packs (cryogenic & promethium) also have a crafting bonus technology. The last key technology has a trigger instead of a research cost as it does not yield anything itself.
- Unlock each group of recipes from one building with a key technology.
- Increase your science pack productivity for each group via a repeatable technology. Applies for the basic as well as the planet specific science pack[3].
You can choose the maximum level of the productivity research yourself, or even disable them completely if you don't like it.
[3]: Where basic sciences are the seven base-game (e.g. military) ones and the other from the DLC (e.g. metallurgy)
Alternative Mod
If you have the need for a simpler integration, you might want to try this mod: OCs Nauvis Science Port, but you can also combine both mods. It keeps the original recipe, but allows it to craft the science pack in the non-Nauvis building. Therefore, it should be even more mod-resillient.
My other mods:
OCs Ammo and Armor -> for easy ammo production OCs Stone Casting -> for all stone-related things OCs Exoplanetary Expansion -> the "modpack" OCs Nauvis Science Port -> similar to this mod
