Space settings
These settings belong to the space, so every scene in it shares them: background, grid, units, lighting, fog and camera.
In the panel, background, grid and units are in the Workspace section. Lighting and fog are in Environment.
Background
Choose a Skybox:
| Skybox | What you get |
|---|---|
Color (color) | One flat colour. |
Gradient (gradient) | A top colour fading into a bottom colour. |
Texture (texture) | An image or an environment map. |
None (none) | No background. In AR, the camera image shows through. |
A background fills the space behind your content. In an AR scene, that covers the real world. None lets the camera image through.
Grid
The grid helps you while you edit. Visitors never see it.
| Setting | What it does |
|---|---|
| Visibility | Shows or hides the grid. |
| Grid type | The plane it lies in: XZ (the floor), XY or YZ. |
| Snap | Objects snap to the grid while you drag them. |
| Scale labels | Labels the grid divisions. |
| Grid distance | How far out the grid fades away. |
| Origin | The colour, size and opacity of the marker at the centre of the world. |
Turn on Snap early. Objects that are almost lined up look like a mistake, and fixing them later means moving them one at a time.
Units
Choose metres, centimetres, millimetres, feet, inches or pixels. Every measurement in the editor uses this unit, including the real-world size of triggers.
The engine works in metres. If you model in centimetres but enter a trigger's size as if it were metres, your content appears a hundred times too big. Pick the unit you use for the real object, and stick with it.
Environment lighting
Environment Light uses an HDRI (a panoramic image of real lighting) or another image to light the scene. It is the biggest single improvement you can make to how a scene looks. It lights objects from every direction, which makes metal and glossy surfaces look right.
| Setting | What it does |
|---|---|
| Map | The HDRI or image. |
| Intensity | How strong the light is. |
| Visibility | On or off. |
Ambient light
Ambient Light adds one flat colour everywhere, with a colour and an intensity. It is simpler than an environment map, but it costs little and is useful for lightening shadows.
Fog
| Setting | What it does |
|---|---|
| Visibility | On or off. |
| Colour | The colour that far-away objects fade into. |
| Start / End | Where the fog begins, and where it is complete. |
| Apply fog to skybox | Whether the background fades too. |
Set the fog colour to match your background. Far-away objects then fade into the horizon instead of ending sharply.
Camera
Mode sets which camera opens on the visitor's device: Auto (by trigger), Front or Back. Face filter scenes need Front.
