Short answer: Open the Theme view from Forge's view switcher. You restyle the reading UI - the textbox, name box, dialogue text, choice buttons, and continue indicator - by clicking the actual element on a live preview and editing it in the inspector. Drag elements to reposition them, resize with edge grips, and nudge with the arrow keys. There are 12 built-in themes to start from, every one of them fully editable, plus image skins, four font sources including your own uploads, a readability hint, undo and redo, and file export so a theme can travel.
Click the thing you want to change
The Theme view shows your game running in a live preview. Click the textbox, the name box, a choice button, or the dialogue text itself, and the inspector opens on exactly that element's controls - colors, transparency, borders, corner radius, typography, animations, and more. A preview toggle switches between your real current scene and a built-in example scene that shows dialogue and a choice menu together, so you can style everything at once.
Layout is direct too: drag an element to reposition it, pull its edge grips to resize, and tap the arrow keys to nudge one pixel at a time (hold Shift for ten). Undo and redo cover everything, so experiments are free.
A theme applies to your whole project - every scene reads with the same styling.
Start from a built-in theme
A presets picker at the top of the inspector offers 12 built-in themes: Vizno Classic, Classic Novel, Glass, Minimal, Manga, Midnight Neon, Royal Velvet, Storybook, Terminal, Sakura, Noir, and Ember. Picking one replaces your current styling (undoable, like everything else).
Nothing about a preset is locked. Every theme is built from the same controls you have, so you can pick the closest look and then change any part of it.
Image skins
Any box - the textbox, the name box, a choice button - can wear an image skin: a picture becomes the frame of the box. A visual guide editor lets you mark which parts of the image are the corners and edges, so corners stay crisp while the middle stretches to fit any amount of text. Choice buttons can carry separate skins for their resting and hovered states.
Fonts
Fonts come from four places: a set of built-in faces, a catalog of bundled open-license families, a wider font library, and font files you upload yourself. The library is tuned to each slot - reading text is offered reading-friendly faces, while the name box can also choose from decorative display faces. Dialogue, the name box, and choice text each pick their own font (choice text can simply match dialogue).
Readability, reader settings, and sharing
- Contrast hint. While you style the textbox, Forge shows a readability check of your text color against the box behind it - flagged as good, ok for large text only, or low - so a beautiful theme stays legible.
- Reader settings still apply. Accessibility settings readers choose, like text size, apply on top of your theme. Your styling sets the look; readers keep control of legibility on their device.
- Export and import. A theme can be exported as a small file and imported into another project. Colors, layout, and effect choices travel; image skins don't, since those images belong to the project's own asset library.
