Editor Command Line Options

This document lists command line options supported by the Lumix Studio editor (studio executable).

Syntax

• Flags use a single dash, for example: -workers 8
• Values containing spaces should be quoted: -data_dir "C:/My Project/"
• Multiple options can be combined.

Options

-data_dir <path>

Sets the project data directory and starts the editor directly in that project.

• Expected value: path to project root directory
• Example: -data_dir "C:/projects/MyGame/"
• Notes:
  • If valid, the welcome screen is skipped.
  • -open is only processed when -data_dir is present.

-open <path_to_world.unv>

Opens a world file on startup.

• Expected value: path to .unv world file
• Example: -open "maps/main.unv"
• Notes:
  • Works only together with -data_dir.

-workers <count>

• Notes:
  • Can be provided multiple times.
