Background, fog & grid
Set the backdrop color, add atmospheric fog, and control the reference grid — the scene-wide environment settings.
Open in the interactive manual →The interactive version has full-text search, a table of contents, and light/dark themes.
Beyond lighting, a few scene-wide settings shape the atmosphere. Find them in Settings ▸ Environment.
| Setting | What it does |
|---|---|
| Environment color | The solid background color. (In Live lighting the procedural sky covers it; you'll see this color in Studio mode.) |
| Fog color | The tint of the fog. |
| Fog type | Linear (fades between a near and far distance) or Exponential (a density value). Fog adds depth and hides the horizon. |
The grid and the ground
A reference grid is drawn at y ≈ 0 to help you judge scale and placement. Toggle it under Settings ▸ Selection + Visual Feedback ▸ Show grid. There's no solid ground plane by default — if you want a real floor (to catch shadows or stand objects on), add a Plane primitive.
Reflections
Both lighting modes load a neutral studio HDRI as the scene's reflection environment, so metallic and glossy materials have something believable to reflect. In Studio mode its strength is the Environment intensity value; in Live mode it dims automatically at night.
