Holocron Toolset: Map Builder (Indoor Map Builder)

The Map Builder creates new playable indoor areas from existing room models, without requiring Blender or any other external 3D modeling tool. Use it when you want to build a new interior area — a Sith tomb, a space station corridor, a cantina back room — by snapping together pre-made room pieces from the game's own model library.

Open it from the Main Window via Tools -> Indoor Map Builder.

Typical workflow: Select a kit (a set of room models from a specific game area) -> place rooms on the canvas -> snap connections between them (shown as green lines) -> File -> Build to output a ready-to-play module to the game's Modules/ folder.

Kits

Kits are collections of room models extracted from specific game areas. The toolset does not ship with kits; download them when first prompted (or via File -> Download Kits). See Kit Structure Documentation for the file format details.
