In Episode 07 of my Ultra Modular Inventory and Interaction System series for UE 5.4, I finally circle back after spending time on the damage system and other projects. This one’s intentionally shorter, and the goal is simple: get the crafting/production/conversion “station” foundation in place so the next episode can focus purely on UI widgets. I walk through how I’m thinking about stations as just another interactable type, and I split them into three categories: crafting stations (hold a button to craft one item), production stations (feed items + fuel and let it run over time), and conversion stations (longer one-to-one conversion with a delay). From there I build the data setup: a Primary Data Asset for station definitions, gameplay tag containers for fuel items, and a gameplay tag → float map for craftable outputs where that float is the “production rate” (used differently per station type). I also create a global Craftable Item Definitions data table that maps an output tag to its required recipe (array of inventory slots). Along the way I fix a small stacking bug (using FoundQuantity vs TargetQuantity), set up station item data + gameplay tags, create a StationBase blueprint with shared interface behavior, and wire Interaction Manager → UI Manager to prove the “Display Station UI” path works. If you get stuck, the Discord is still the fastest way to get help.
