Lighting
Point Light
A point light is a light source located at a point in space that emits light rays in all directions, similar to a light bulb in real life.
Point lights have 3 main characteristics: color (color), intensity (intensity), and range (distance). Areas beyond the range will not receive light from the point light, and the intensity of the light decreases as the distance from the light source increases.
| Property | Description |
|---|---|
| Intensity | Controls the intensity of the point light, higher values mean brighter light |
| Color | Controls the color of the point light, default is white |
| Distance | Range within which the light affects, light intensity decreases with distance |
| Culling Mask | Controls which objects the light should illuminate, default is Everything. Needs to be used with the Layer of the Entity |
