This article was prepared with AI assistance based on an analysis of the current Lumina Studio source code, existing Wiki content, and relevant workflows. It has been checked against the current version, but omissions or details that become outdated may remain as the software evolves. If you find an error or have a clearer explanation, example, or suggestion, please leave a comment on this page or propose an edit on GitHub.
Navigation, Language, Theme, and Connection Status
The header contains the product identity, workspace navigation, and global status controls. Changing pages does not start Preview, Generate, or Save, and the current editing state normally remains available.
Primary pages
| Page | Purpose |
|---|---|
| Converter | import artwork, choose a colour source and structure, Preview, and generate 3MF |
| LUT Management | manage LUTs, create calibration boards, extract LUTs from photographs, and inspect or compare LUTs |
| Material Management | manage material archives, generate or extract gradient cards, and query layer recipes |
| Vectorizer | convert a bitmap into SVG for further editing or transfer to Converter |
| Settings | select the machine, nozzle, and slicer, and manage compute, cache, and interface options |
LUT Management and Material Management have their own secondary pages. Returning to either workspace keeps its current valid secondary page; an invalid stored page falls back to that workspace's default.
Converter secondary pages
- Core Settings: image, source, dimensions, backing, mode, common advanced options, and Actions;
- Color Adjustment: 2D Preview, selections, colour replacement, recipes, and colour groups;
- Advanced: Relief, Outline, Cloisonné, Transparent Coating, Keychain Loop, Fridge Magnet, Puzzle, and related structure controls.
Core Settings and Advanced use movable panels. Color Adjustment is a full-screen colour workspace, so Panel Controls only lists panels that actually exist on the active page. See Show, Collapse, Move, and Reset Panels.
Language and theme
The language button reads EN in Chinese and 中 in English. Switching language preserves
the active page, input values, and Preview while replacing the interface copy.
The theme button switches between light and dark presentation. It does not change the image, recipe, model, or export. On a narrow window, some labels collapse to icons and the navigation rows can scroll horizontally.
Connection status
The status at the right of the header reports whether the frontend can reach the Lumina backend:
- green: the latest
/healthcheck returned normally; - red: the latest check failed or the backend was unreachable;
- checking: the first result has not arrived.
Lumina checks once when the page loads and then every five seconds. Green only confirms current frontend-to-backend communication; it does not prove that a particular LUT, image, temporary session, or generation task is valid. When the badge is red, verify that the Lumina backend is running before retrying the action.
Update announcements
When a newer unread announcement exists, Lumina presents recent update entries after startup. Closing dismisses the dialog for the current session. Do not show this version again records the latest announcement version in local browser storage. That reading state is not uploaded and does not change Converter settings.
What page changes preserve
The interface retains current control values, selected pages, and panel layout. Device settings also use best-effort backend synchronisation. Temporary Previews, download links, and file sessions still expire. For durable work, keep the share card, JSON, 3MF, source artwork, and the actual LUT or material archive.
