Cluster Decoration
Attaches external meshes (leaves, flowers, fruit) to the skeleton.
The Cluster Decoration node attaches external geometry (leaves, flowers, thorns, fruit) to the plant. Unlike Surface Decoration, which skins the branch itself, it instances objects onto the skeleton, can deform them to follow branch curvature, and can select between variant inputs by attribute.
Inputs
| Input | Description |
|---|---|
| Input 0: Graph | The growth graph. |
| Input 1+: Geometry | The meshes to instance (e.g. a leaf model). Multiple inputs can be connected to provide variant geometry. |
Attributes
| Attribute | Description |
|---|---|
u | Consumed to drive placement along the branch. |
width | Consumed to scale instances to branch thickness. |
orient | Consumed orientation along the branch. |
Outputs
| Output | Description |
|---|---|
| Output: Graph | The graph with cluster instructions. |
Intrinsics
| Attribute | Description |
|---|---|
instance | Instance attributes on the output points. |
Parameters
Placement
| Parameter | Description |
|---|---|
| Density | How many instances per unit length. Controls the overall coverage of decorations along the branch. |
| Pattern | Phyllotaxis arrangement: Spiral, Opposite, or Whorled. Determines the botanical arrangement pattern of instances around the branch. |
| Align | Orientation rules for each instance: tumbling, facing up, or facing outward from the branch. |
Variation
| Parameter | Description |
|---|---|
| Scale | Randomise size of instances. Adds natural variation to the decoration sizes. |
| Variant Attribute | Attribute to drive which input mesh is used. Allows different parts of the plant to receive different geometry variants. |
