Cell of Interest (COI) is a location on a building which corresponds to some form of interaction between the building and the world. There are three types which are: material delivery, material drop-off, and Dupe interaction. In most cases, the three types of COI are located in the same location. It's known as Tile Of Interest (TOI) by the community but should be named Cell of Interest because the location is a cell, not a tile.

Cell of interest type[]

  • Delivery cell - The cell which accepts item deliveries to the building.
  • Material drop-off cell - The cell where the building item output are dropped, e.g food from an electric grill.
  • Dupe interaction cell - The cell that the Dupes must occupy in order to operate the building. Dupes exist in the bottom cell for most purposes.

List of buildings' Cell of interest[]

  • Algae Distiller: Delivery and material drop-off at the middle bottom cell
  • Apothecary: Delivery, Dupe interaction and drop-off all at the bottom left cell.
  • Arcade Cabinet: Dupe interaction on either bottom left or right cell, both can be used at the same time.
  • Bottle Emptier: Liquid output at adjacent bottom cell, facing the faucet.
  • Coal Generator: Delivery at bottom middle cell.
  • Comfy Bed: Dupe interaction at the middle left bottom cell.
  • Compost: Delivery and Dupe interaction at the bottom left cell. Material drop-off at the bottom RIGHT cell, despite the animation visibly showing the middle.
  • Conveyor Loader: Delivery at the conveyor output cell (the one with the arrow).
  • Conveyor Receptacle: Pick up at the conveyor input cell (the one at the fat end).
  • Cot: Dupe interaction at the bottom left cell.
  • Critter Feeder: Bottom cell.
  • Crops: Harvest at Plant's bottom cell. Delivery at Planter Box or Farm Tile. The same is true for natural growing plants.
  • Desalinator: Dupe interaction and material drop-off at the middle left bottom cell (you need to empty this one manually, maximum ~950kg).

  • Observatory: Dupe interaction at middle left bottom cell.
  • Oil Refinery: Dupe interaction at the middle left bottom cell (animation is off again).
  • Oil Well: Liquid output at rightmost bottom cell, gas output at middle left bottom cell.
  • Ore Scrubber: Dupe interaction at bottom middle cell.
  • Outhouse: Delivery, Dupe interaction, material drop, Morb spawn- all at the bottom left cell.
  • Oxylite Refinery: Delivery and drop-off at the bottom middle cell.
  • Petroleum Generator: Liquid output at rightmost bottom cell.
  • Polymer Press: Material drop-off at the bottom left cell. If it's flipped, material drop of is one cell outside of its building area.
  • Power Control Station: Delivery, Dupe interaction and drop-off at bottom left cell.
  • Printing Pod: Drop-off on either middle cells. Don't know if this means that a sweeper need to be able to reach both. Weight plate gives no signal.
  • Ration Box: Bottom left cell.
  • Refrigerator: Bottom cell.
  • Research Station: Delivery and Dupe interaction at bottom left cell.
  • Rock Crusher: Delivery, Dupe interaction, drop-off - all at the middle left bottom cell. Dupe animation looks like it's in the left most cell, don't be fooled.
  • Shearing Station: Dupe and critter interaction at middle bottom cell. Material drop of is randomly dropped around bottom left cell (can be located in the middle, giving no pressure registration)
  • Shower: Dupe interaction at the bottom left cell.
  • Sink: Dupe interaction at the bottom left cell.
  • Skill Scrubber: Middle bottom cell.
  • Soda Fountain: Dupe interaction at bottom left cell.
