Noise Effector
The Noise Effector samples a 3D noise field at each point in world space and writes the result as a per-point direction vector, producing spatially-coherent variation across the structure. It can be plugged into any node accepting effectors (typically Grow or Assembly Decoration). Curl noise is supported for fluid-like, divergence-free turbulence; strength and scale can be modulated through mapping.
Inputs
- Parms (Optional). Connect to the main parameter stream.
- Output: Effector. Connect to an effector input on a Grow node.
Parameters
Noise
| Parameter | Description |
|---|---|
| Type | The noise algorithm: Perlin, Simplex, Curl, and others. Curl noise produces divergence-free turbulence that creates fluid-like swirling patterns. |
| Frequency | Size of the noise features. Lower values create larger, smoother variations; higher values create finer, more detailed turbulence. |
| Amplitude | Strength of the force. Controls how strongly the noise field influences growth direction. |
| Offset | Animation or spatial offset. Use this to animate the noise field over time or shift the pattern in space. |
Notes
- The effector samples position
Pin world space; it does not consume graph attributes directly. - Curl noise is particularly useful for creating organic, flowing growth patterns without divergence artefacts.

Mapping Template
Authoring node for defining mappable parameters on a target HDA. Used when building custom modules or wrappers that need their own promotable parameter surface.
Pivot Edit
Interactive state for manually placing pivots on input assembly geometry when auto-rigging fails. Inner utility of the Assembly Resource.
