1  # VGP – Garden Resources × Medieval Overhaul: Smelter Patch
 2  
 3  A small compatibility patch that lets you smelt Vegetable Garden Project – Garden Resources intermediary ores (“leaves”/shrooms) at Medieval Overhaul’s smelter buildings. It also re-flavors Steel Shrooms into Iron Shrooms and updates the resulting product to Medieval Overhaul’s iron ingots.

 6  ## What this patch does
 7  
 8  - Adds smelting processes for VGP GR intermediate resources to MO’s processing buildings:
 9    - Medieval Smelter (DankPyon_Smelter)
10    - Blast Furnace (DankPyon_BlastFurnace)
11  - Supported inputs and outputs (via ProcessorFramework):
12    - RawSteelLeaf → Iron Ingots (DankPyon_IronIngot) at 25% efficiency
13    - RawPlasteelLeaf → Plasteel at 25% efficiency
14    - RawGoldLeaf → Gold at 25% efficiency
15    - RawSilverLeaf → Silver at 25% efficiency
16    - RawUraniumLeaf → Uranium at 25% efficiency
17  - Renames and re-describes VGP content to fit MO:
18    - “Steel Shrooms” become “Iron Shrooms” (and the plant becomes “iron shroom tree”).
19    - VGP’s extraction recipes now produce Medieval Overhaul Iron Ingots:
20      - ExtractRawSteelLeaf → 4 × Iron Ingots from 16 shrooms
21      - ExtractBulkSteelLeaf → 16 × Iron Ingots from 64 shrooms
22  - Note: This is a bit “cheaty” compared to VGP’s Electric Smelter as Medieval Overhaul processors do not enforce the same skill requirements; pawns without Crafting can still run the processes.

52  ## Save-game compatibility
53  
54  - Can generally be added to existing saves that already use Medieval Overhaul and VGP – Garden Resources. The patch only adds ProcessorFramework processes and applies label/recipe patches.
55  - Removing the patch from an in-progress save may orphan jobs or remove patched labels/recipes. Do so at your own risk; finish active bills first.
56  
57  
58  ## Technical details
59  
60  - Uses PatchOperationAdd to append ProcessDefs to MO’s Smelter and Blast Furnace.
61  - ProcessDefs are defined under `1.6/Defs/ProcessorDef/SmeltingDefs.xml` with 0.25 efficiency.
62  - Renames and recipe swaps are in `1.6/Patches/VGPGR.xml`.
63  - No C# assemblies; this is pure XML patching and ProcessorFramework use.
64  
65  
66  ## Known limitations
67  
68  - Medieval Overhaul’s processors do not replicate VGP’s higher skill requirements from the vanilla Electric Smelter. Production is therefore easier than intended by VGP.
