# Screenshot a three.js scene

1. `open` the page once: `cwd` and `url: "index.html"` (the folder is served over HTTP), or `command: "bunx vite"` for a dev server. The reply lists the files it loaded and any that failed.
2. `look`: the picture is in the reply, with the named objects on screen and a `Never visible:` line for each one no look has seen, with its size and where it is.

One mode per call: `target: "<name>"` for four views of one object, `cameras` for several positions in one picture, `sheet` for several moments or stages, `opening: true` for the first seconds after load, `zoom` for a box enlarged, `scroll` for a page driven by scrolling. After an edit, the next `look` reloads the page by itself and says which fault lines closed. What its `Lighting:`, `Surfaces:` and other lines mean, and how to close one: `../threejs-game/references/lighting.md`.

Building or changing the page: the `threejs-game` skill (`../threejs-game/SKILL.md`) says what every tool shows. If `open` and `look` are not among your tools, the paprika3d MCP server is not installed: it runs as `npx -y paprika3d serve` (stdio), and https://paprika3d.com/docs/install has each agent's line.
