Indoor Smelting & Blacksmithing
This mod adds traditional metallurgy to the game with the goal of having a feasible option for indoors production of iron plates and other items when you just want to do a city based run, although this process is less efficient and more labour intensive than regular outdoors refineries for the sake of balance and immersion.
I had to use existing resources since I’m no real modder, there are 3 levels that can be normally researched, you’ll need to build an ore smelter, blacksmith, charcoal burner, gathering station for "combustible material" (i.e wood and similar) and relative storages in order to have a self sufficient artesanal production cycle.
I did this a long time ago, now backing it up for eventual future use as I quite liked it in my games, iirc it’s fully functional but it may lack an updated description here and there, you can let me know if you run into any problems.
