Directional Light
A sun-style infinite light aimed by heading and pitch.
The Directional Light node lights everything from one direction, wherever it sits.
- Heading, Pitch, Roll
- Intensity, Ambient, Cast Shadows
- Found in the node graph under Surfaces → Lighting

Inputs and outputs
| Port | Type | Purpose |
|---|---|---|
| Surface / Texture | Surface | The chain. |
| Origin Object | Surface | A Null to parent to. |
| Surface | Surface | The chain with the light. |
Parameters
- Aim From X / Y / Z — the shadow origin.
- Heading (default 45), Pitch (default −54.7), Roll.
- Color, Intensity (0–20, default 1.5), Ambient (default 0.25).
- Cast Shadows (default off) with the shadow quality block.
Every slider has a per-parameter animation bar, so it can be animated, audio driven, or MIDI mapped.
Examples
Low sun — Pitch −15, warm Color, Cast Shadows on.
Troubleshooting
Position does nothing — a directional light has no position; only its angles matter.
