SurtlingFuel
Tired of burning through wood to make coal? Put those surplus Surtling Cores to work! This mod lets you use Surtling Cores as a premium fuel source in both the Smelter and Blast Furnace.
Features
- Surtling Cores as fuel — walk up to a smelter or blast furnace and add cores directly
- 4x fuel value — 1 Surtling Core provides 4 coal-equivalent fuel (smelts 2 ores)
- 2x smelting speed — ores process twice as fast while burning core fuel
- Cores take priority — if you have cores in your inventory, they'll be used first over coal
- Fully configurable — tweak all values via BepInEx config file
Configuration
After first run, edit BepInEx/config/com.dejan.surtlingfuel.cfg:
| Setting | Default | Description | |---------|---------|-------------| | SmelterFuelPerCore | 4 | Coal-equivalent fuel per core in the smelter (2 coal per ore, so 4 = 2 ores) | | BlastFurnaceFuelPerCore | 4 | Coal-equivalent fuel per core in the blast furnace (2 coal per ore, so 4 = 2 ores) | | SpeedMultiplier | 2.0 | Smelting speed multiplier while burning cores | | PreferCoresOverCoal | true | When true, cores are used before coal. When false, coal is used first. Client-side only. |
