geo/PointLight
A light radiating in every direction from a point, like a bare bulb.
Lights
Position it with an upstream transform; its rotation does not matter. Intensity falls off with distance following decay and reaches zero at distance. Point lights do not cast shadows yet.
Parameters
| Name | Type | What it does |
|---|---|---|
| color | Color | Light color. |
| intensity | Float | Light brightness. Scales the color's contribution. |
| decay | Float | How fast the intensity falls with distance. 2 is the physically correct inverse-square falloff. 0 keeps the intensity constant. |
| distance | Float | Reach of the light, in world units. The contribution fades to zero at this distance. 0 means unlimited. |
| displayHelper | UInt8 ONLY_IN_EDITOR · ALWAYS · NEVER | When to draw the light's viewport helper. |
