NEVER SORT BY COLOR

MOC IMPORT

How do you import a MOC?

Open the pause menu and use Load MOC. The developer says it reads files from the LDraw OMR library. Minifigs are refused.

MOC means My Own Creation. In this game a book is a parts list, and the finished model stays in the workshop. Two threads ask how to import one. The developer’s own reply on the free-build thread is the part I trust: Load MOC can open any file hosted on library.ldraw.org/omr, missing parts are filled in, and minifigs are not allowed. There is no free-build sandbox beyond that.

Steps that are actually written down

  1. Pause, then choose import moc / Load MOC.
  2. Pick an LDraw OMR file. The 23 Aug studio post explicitly supports Brick Studio .io and LDraw .ldr files. A file-size cap is not published.
  3. Set Model Settings: Display only, Explore, Car, Plane, or Helicopter. Choose which way the nose points, where rotors sit, and the waterline. The 10 Nov notes say you can change this later by aiming at the book or the finished model and pressing Label.
  4. Pull parts with the locator and the labels, the same way a built-in book works.
  5. If the book is short, Options → Restore Missing Pieces also scans imported books and drops gaps near the start. That is the 20 Oct note, and two later threads say players still use it on imports.
  6. On Steam Deck and Steam Machine the Import MOC button is hidden. There is no file browser. Use a built-in book there instead. See platforms.

What players hit after a large import

One thread reports a large import missing 91 pieces across 68 part types, with some parts that have no mesh or label. Another says there is no control that deletes an imported MOC. I am keeping both as player reports. The studio has not posted a delete command, and I will not invent one.

Built-in models, so you can compare scale

The 23 Aug “Master Builders” note lists piece counts the studio is allowed to use: USS Iowa 8,108; Haunted House 4,090; Theatre 3,763; Atlanta 3,583; Antique Store 3,257; Fletcher 2,252; Crane on 18 wheels 1,425; Coffee Stand 1,489; Cherokee 806; Crane 773; Dump Truck 714; Tiller 708; Viper 660; Loader 373; Articulated Hauler 308. Those are studio figures, separate from anything you import.

Questions

Pause menu, Load MOC, then an LDraw OMR file. The developer posted that path. Minifigs are refused.

Is there a way to remove an imported MOC?

Players say they cannot find a delete control. No studio note I have names one.
