Managing open files
Every file opened in a session stays in the sidebar's Models list until it is closed.
The Models list
Each row shows the file's format and its name. A file that composes other files, such as a USD stage, gets a disclosure dropdown with its child assets indented beneath it. A child row is fully selectable, so a referenced layer can be viewed on its own.
Sorting and searching
The sort control sits in the list's Open header and offers Date Added, Name (A–Z), Name (Z–A), and File Format. The same preference appears as Sort Files By in Settings ▸ General ▸ Files, and the two controls write the same setting.
The search field above the list filters it. When a query is active, a composite asset expands to show only the children that match, and the disclosure state is restored when the query is cleared.
The row context menu
| Command | Effect |
|---|---|
| Compress Model | Opens the compression export dialog. Enabled for glTF and GLB only. Becomes Compress Selected Models for a multiple selection |
| Reveal in Finder | Shows the file in the Finder |
| Reload | Re-reads the file from disk, discarding every unsaved edit |
| Close | Closes the file. Becomes Close Selected Models for a multiple selection |
Reveal in Finder and Reload apply to a single file and are hidden when several are selected.
Unsaved changes
Solidly tracks whether each open model differs from what is on disk. File ▸ Save is disabled until the selected model has a change, and File ▸ Save All is disabled until at least one open model does. Closing a model with unsaved changes asks for confirmation unless that confirmation is turned off in Settings ▸ Advanced ▸ Behaviour.
Switching between models
Models that are open but not displayed are kept in GPU memory so that switching back to one is immediate. The budget for that cache is set in Settings ▸ Graphics ▸ Performance ▸ Model Cache; below the budget, a model is reparsed from disk instead. Settings ▸ Advanced ▸ Caches reports what each cache holds and clears them on demand, which never affects a file on disk or an unsaved edit.
