| Lights | |
|---|---|
| Made with | Functional > Create Omni Light / Create Spot Light |
| What it is | Point lights that shine in every direction, and spot lights that shine in a cone |
| In the game | Yes, it is exported with the map |
A map is lit by the sun (set in Map Config > Environment), the sky's ambient light, and the lights you place:
- An Omni Light shines in every direction from a point: a lamp, a bulb, a fire.
- A Spot Light shines in a cone: a floodlight, a torch beam, a window's shaft of light.
Lights are baked into the lightmap when you bake (see Lighting and lightmaps).
Placing a light
- Choose Functional > Create Omni Light or Create Spot Light.
- Click where it goes. A spot light points along its forward direction; aim it with the Rotate tool.
- Set its colour, brightness and range in the inspector.
In the editor an omni light shows a wireframe sphere at its range and a spot light a cone and an arrow, both in the light's colour. Their strength is Light Gizmo Opacity in Settings.
Inspector
Besides its own two settings, a light has all the standard light settings. The ones you will use most:
| Setting | Type | Default | What it does |
|---|---|---|---|
| Point Name | Text | empty | A label shown above it in the editor. |
| Show Visualization | Check box | On | Draw the range sphere or cone. Turn it off where many lights crowd the view. |
| Light Color | Colour | White | The light's colour. |
| Light Energy | Number | 1 | How bright it is. |
| Light Indirect Energy | Number | 1 | How much it adds to bounced light in the bake. |
| Light Bake Mode | List | Dynamic | How the light takes part in the lightmap bake. Disabled leaves it out of the bake. |
| Shadow Enabled | Check box | Off | Cast real-time shadows. Shadows are expensive; use them only where they matter. |
| Omni Range | Metres | 5 | Omni. How far the light reaches. |
| Omni Attenuation | Number | 1 | Omni. How quickly it fades with distance. |
| Spot Range | Metres | 5 | Spot. How far the cone reaches. |
| Spot Angle | Degrees | 45 | Spot. How wide the cone is. |
| Spot Angle Attenuation | Number | 1 | Spot. How softly the cone's edge fades. |
| Distance Fade | Group | Off | Fade the light out beyond a distance from the camera, to save performance in big maps. |
In the 3D skybox
An omni or spot light placed inside the 3D skybox miniature lights only the skybox, scaled up with it.
