So I'm assuming WorkshopMaxProductionPerNPCFood is the variable that affects how much food any npc in your settlement can farm, which is set to 6. I tried changing this in the GECK, but it did not seem to do anything. I must be missing something. However, we could attribute that to my limited knowledge of changing global variables via GECK. Most of my personal mods are general crafting mods, using Fallout 4 assets. I attempted to use console, as well. set WorkshopMaxProductionPerNPCFood to 12 However, this also showed no effect. Oh, woe is me.
