About Heavy Fluid Overhaul
From ficsit.appThe humongous pipe emulator that reduces all fluids in recipes, resource extractors and power generators
Heavy Fluid Overhaul ('HFO') is an extensive mod which can greatly reduce the quantity of all fluids required by production recipes and power generators, as well as reducing the fluids produced by Resource and Water Extractors. This proportional reduction in both supply and demand simulates the throughput of higher-tier pipes, while working around the current technical limitations of Satisfactory's fluid modelling system (fluid flow rates are limited to the 600m³/min maximum of vanilla Mk.2 Pipes).
Unlike other mods, this one does NOT add any recipes or machines to simulate "compressed" fluids, and can be safely added mid-game without the burden of additional logistics.
> This mod can be configured through the __Mod Savegame Settings__, which is an ESC menu that only appears after a save file has been loaded or when starting a new game session.
> Note: You must save and reload your save file for the new settings to take effect.
There are plans to add support for popular mods that add custom machines and use fluids, but this task takes time, since most of them are closed source. Alternatively, you can contact mod's authors and ask them nicely to add support to HFO.
Summary
- DEMAND: Automatically reduces the fluid requirements of all recipes and power-generators by 2x (default), 5x, or 10x.
- SUPPLY: Separately sets the fluid output of each Extractor category below, to 1.0x, 0.5x (default), 0.2x, or 0.1x:
- Fluid Resource Extractors (eg: Oil Extractors, Resource Well Extractors, etc.)
- Water Extractors
- Can optionally upscale the cost of building pipelines by a custom value.
- Can optionally limit the fluid flow rate of vanilla Mk.1 and Mk.2 pipes to 150m³ and 300m³ respectively (useful to maintain balance when more extreme multipliers are used in the above settings for demand/supply, eg: 5x/0.2x and 10x/0.1x)
- Works with any modded recipes or fluids, as well as modded machines which are based on vanilla machines and do not contain custom logic.
