This mod adds new blocks, ores, and machines for a fully immersive metal forging experience. With it, you can process ores and melt down precious metals.
Some names and models are inspired by Tinkers’ Construct, and full credit goes to them if you notice any similarities.
This mod is not related to Hephaestus (Fabric). While both mods have similar concepts, they are completely different projects.
The mod includes integration with AllTheOres and FTB Materials, meaning all alloys and ores from that mods can be processed through the Hephaestus system.
The mod is still in development and not in its final version. More blocks and machines may be added in future updates. Please keep this in mind when updating: always back up your world and check the changelog to stay informed about changes between versions.
