Lights
The inspector displays different properties depending on the type of light selected. This page covers the settings available for each light type.
Common Light Properties
All lights share these base properties:
| Property | Description |
|---|---|
| Color | The color of the emitted light |
| Intensity | Brightness of the light |
Ambient Light
Ambient light provides uniform illumination to all objects in the scene regardless of their position or orientation. It has no direction and does not cast shadows.
| Property | Description |
|---|---|
| Color | Light color |
| Intensity | Brightness |
TIP
Use ambient light to set a base illumination level so that objects in shadow are not completely black.
Sun Light (Directional)
Sun light emits parallel rays in a single direction, simulating distant light sources like the sun. It supports shadow casting.
| Property | Description |
|---|---|
| Color | Light color |
| Intensity | Brightness |
| Cast Shadow | Enable/disable shadow casting |
| Shadow Map Size | Resolution of the shadow map (higher = sharper shadows) |
| Shadow Bias | Offset to reduce shadow artifacts (shadow acne) |
| Shadow Camera | Near, far, and FOV settings for the shadow camera frustum |
Spotlight
Spotlight emits light in a cone shape from a point, like a stage light or flashlight.
| Property | Description |
|---|---|
| Color | Light color |
| Intensity | Brightness |
| Distance | Maximum range of the light (0 = infinite) |
| Decay | How the light fades with distance |
| Angle | Width of the light cone (in radians) |
| Penumbra | Softness of the cone edge (0 = hard, 1 = fully soft) |
| Cast Shadow | Enable/disable shadow casting |
| Shadow Map Size | Shadow resolution |
| Shadow Bias | Shadow offset to reduce artifacts |
Point Light
Point light radiates equally in all directions from a single point, like a light bulb.
| Property | Description |
|---|---|
| Color | Light color |
| Intensity | Brightness |
| Distance | Maximum range (0 = infinite) |
| Decay | Rate of falloff with distance |
| Cast Shadow | Enable/disable shadow casting |
| Shadow Map Size / Bias / Camera Near & Far | Shadow quality and artifact controls |
Hemisphere Light
Hemisphere light simulates outdoor lighting with a sky color above and a ground color below, creating a natural gradient.
| Property | Description |
|---|---|
| Sky Color | Color from above |
| Ground Color | Color from below |
| Intensity | Brightness |
