The toolbar Options menu configures the script editor — how composites and entities are shown, Viewport behaviour, save/launch helpers, and more.

Most items are checkboxes that stick between sessions. Controls opens a shortcut reference, and Manage Game Directories opens the multi-install manager.

• Use File Browser Composite Viewer — switches the composite list to a file-browser style panel (off by default).
• Search Only Composite Names — composite search matches only the composite name, not folder path segments (off by default).

• Show ShortGuids — shows entity IDs (ShortGuids) in lists, names, breadcrumbs, aliases/proxies, and global search (off by default).
• Populate All Node Pins When Created — new flowgraph nodes get every pin added automatically (on by default).
• Set Node Colours — opens a colour picker for flowgraph node types (Functions, Instances, Proxies, Aliases, Variables). Reset restores the defaults.
• Show Confirmation When Deleting Node — asks before removing a flowgraph node (on by default).
• Give Option To Delete Entity When No Nodes — after the last node for an entity is removed, asks whether to delete the entity too (on by default).

Shown when the Viewport is available. Full Viewport usage is covered in the Viewport docs.

• Highlight Aliases — orange highlight on entities targeted by parameterized aliases in the active composite (on by default).
• Highlight Proxies — blue highlight on proxy targets when you've stepped into a nested composite (on by default).
• Show Camera Position — shows camera X/Y/Z while moving (off by default).
• Render Wireframe — draws ModelReference meshes as wireframe (off by default).
• Hide Nested Script Entities — hides render previews for script entities in nested composites; ModelReferences stay visible (off by default).

• Show Confirmation When Saving — shows a “Saved changes!” popup after a successful save (on by default).
• Use Textured Model View — model previews try to load textures/materials (on by default).
• Keep Global Search Window Open — after jumping to an entity from global search, the search window stays open (off by default).
• Reset UI Layouts — restores the default window size and dock panel layout. If the Viewport is open, it's kept and repositioned.
• Write Instanced Resources (Experimental) — experimental save option for regenerating instanced resources. Not used by the public build yet (off by default).
• Set Numeric Step — sets how much position and rotation values change when you nudge numeric fields in inspectors (defaults: position 0.1, rotation 1.0).
• Save Commands PAK and BIN — when saving an uncompressed Commands file, also writes the alternate extension (PAK↔BIN). Compressed levels always save as BIN (on by default).
• Open Game On Save — after save, launches into the level you're editing. Uses some of the same patch flags as Launch Game, but skips extras from that dialog such as Cinematic Tools / Hot Reloading (off by default).
• Show Game Platform — appends the detected platform (e.g. Steam) to the window title — handy with multiple installs open (off by default).
• Write Compressed — status only: shows whether the loaded level's Commands are compressed. Not user-togglable.
• Reset Render Filters On Load — when loading a level, turns all Viewport render filters off (shown only if the Viewport is available; off by default).

Opens a read-only Controls window with shortcut reference tabs:

• Flowgraph Controls — zoom, pan, move nodes, links, pin shortcuts
• Model Viewer Controls — zoom, rotate, move, recenter
• Viewport Controls — camera, selection, step in/out, gizmos, hide/unhide (see also the Viewport docs)
• Entity List Controls — stepping into composite instances from the entity list

Opens the Game Directory Manager — register installs, set the default, and open extra editor windows. Available only in the primary OpenCAGE window (the one launched from Steam), not in child editors opened for other installs.
