The REI (Realistic Energy Industrial) mod is a medium-sized industrial mod. It mostly uses the existing equipment from the original Vanilla Minecraft.
This includes basic materials such as:
- Refined Iron
- Refined Iron Ingot
- Reinforced Ingot
- Titanium
- and much more!
And crafting tools using Reinforced Ingot!
REI also changes Minecraft's crafting mechanics; for example, smelting iron ore will no longer produce Iron Ingot immediately, but rather pig iron raw, and you have to smelt it again to get Iron Ingot,...
