Customize Prospect
Three appearance settings, one place: Settings > General. Theme and backdrop apply hot, the window changes while you watch. The language waits for the next start.
The theme
Section titled “The theme”Dark, light, or follow the system. Three buttons, immediate effect: no restart, no “takes effect later”. A fresh install starts dark. “Follow the system” hands the choice to your OS and keeps listening: if your machine switches to light, Prospect follows.
The documentation shows both themes, and so does this site: the gallery captures switch with the page theme.
The window backdrop
Section titled “The window backdrop”Eleven built-in backdrops, all captured in the game, from “Turquoise pools” (the original) to “Crystal vein”. They sit in a thumbnail grid under Settings > General; click one and the window changes right away, no restart. The choice sticks across launches.
You will notice the thumbnails are sharp while the applied backdrop is soft: every image is softened and dimmed ahead of time so the glass panels and the text stay readable on top of it, whichever backdrop you pick. The backdrop dresses the window, it does not compete with it.
The language
Section titled “The language”English or French. On first start, Prospect follows your system language; after that, the selector in Settings changes it. Unlike the theme and the backdrop, the choice takes effect the next time Prospect starts, and the screen says so right under the selector. This setting is about the launcher only: the game’s language is set inside Vintage Story.
