3D node
Light
Defines a single light source for Render 3D — Directional, Point, Sun, Ambient, or Spot — with azimuth/elevation/distance placement, color, intensity, falloff, and cone angle/softness for spots. Can also orbit automatically over time.
What it does
Light is a 3D node: it builds, changes or lights geometry that Render 3D turns into a picture. It has no input and gives light out, so it starts a chain.
Try it
Use a Spot light with a narrow cone angle and low penumbra for a hard-edged theatrical spotlight look.
Inputs and outputs
Inputs
- None. It starts a chain.
Outputs
- light out
Controls
Every control with a range can be driven by a modulator, a note, an audio level or a sketch.
| Control | Range or options | Default |
|---|---|---|
| type | Directional, Point, Sun, Ambient, Spot, Area | 0 |
| orbit | -180 to 180 | 51.5662003 |
| elevation | -85.944 to 85.944 | 51.5662003 |
| distance | 0.2 to 20 | 4 |
| intensity | 0 to 5 | 1.20000005 |
| cone angle | 5 to 85 | 45 |
| penumbra | 0 to 1 | 0.200000003 |
| orbit / beat | -1 to 1 | 0 |
| width | 0.05 to 10 | 1 |
| height | 0.05 to 10 | 1 |
