# Look presets

Ready-made looks: blocks of existing scene settings (`meta.environment.sky`, `meta.environment.ambient`, `meta.render`) for a scene. An agent puts one on in one call, `look.apply {look: "sunny-midday"}` (toolset `view`): those three blocks replaced whole as one `scene.patch`, nothing else touched, one undo. Each look is a recipe called `look-<name>`, so an agent can also read it as a recipe (`argus://recipes/look-sunny-midday`) and copy the blocks by hand, and a new look is a new recipe. None of them changes a scene that does not use it.

| Look | Use | Recipe |
|---|---|---|
| Sunny midday (`sunny-midday`) | `meta.environment.sky`, `ambient` 0.4 and `meta.render` from the recipe's scene: a blue sky, fair cumulus (HD), a high sun that drives the scene's light, light haze, `aces` with the `bright-day` grade. | `fixtures/recipes/look-sunny-midday` |

The fields themselves are documented in docs/SKY.md (sky, atmosphere, clouds, `sunFromSky`) and docs/RENDERING.md (tonemap, exposure, `look`).
