Space settings
These belong to the space, so every scene inside it shares them.
Background
| Skybox | What you get |
|---|---|
color | a flat colour |
gradient | a top and a bottom colour |
texture | an image or environment map |
none | no background — the camera feed shows through in AR |
noneA background fills the space behind your content, which in an AR scene means covering the real
world. none is what lets the camera through.
Grid
The grid is an editing aid — it is not part of your published experience.
| Setting | What it does |
|---|---|
| Visibility | show or hide it |
| Plane | XZ (floor), XY, or YZ |
| Snap to grid | objects snap while you drag them |
| Show scale | label the divisions |
| Fade | how far out the grid fades away |
| Origin marker | colour, size and opacity of the world origin |
Snap to grid is worth turning on early. Objects that are almost aligned look like a mistake, and fixing it later means re-placing things one at a time.
Units
Metres, centimetres, millimetres, feet, inches or pixels. Every measurement in the editor is shown in this unit, including physical trigger sizes.
The engine works in metres. If you model in centimetres and set a trigger's physical size as though it were metres, your content arrives a hundred times too large. Pick the unit that matches how you think about the real object and stay with it.
Environment lighting
An HDRI or image used as a light source. This is the single biggest improvement you can make to how a scene looks: it lights objects from every direction with a real environment, which is what makes metals and glossy surfaces read correctly.
| Setting | What it does |
|---|---|
| Map | the HDRI or image |
| Intensity | how strong it is |
| Visibility | on or off |
Ambient light
A flat colour added everywhere, with a colour and an intensity. Cruder than an environment map, but cheap and useful for lifting shadows.
Fog
| Setting | What it does |
|---|---|
| Visibility | on or off |
| Colour | the colour distance fades toward |
| Near / far | where fog begins and where it is complete |
| Apply to skybox | whether the background fades too |
Set the fog colour to match your background and distant objects dissolve into the horizon rather than ending abruptly.
Camera
The camera mode decides which one a visitor's device opens with: automatic, front-facing, or the main rear camera. Front-facing is what a face-filter scene wants.
