3D & SimulationSurface Operators
Smooth
Laplacian relaxation of vertex positions.
The Smooth node relaxes the mesh, rounding corners and evening out noise.

- Iterations and Strength
- Found in the node graph under Surfaces → Topology
The image on the right is the example patch itself. Drag and drop it onto the app, or load it with File → Load, to open the full graph. A subdivided sphere, smoothed.
Inputs and outputs

| Port | Type | Purpose |
|---|---|---|
| Surface | Surface | The mesh. |
| Surface | Surface | The result. |
Parameters
- Iterations (1–20, default 2), Strength (0–1, default 0.5).
Every slider has a per-parameter animation bar, so it can be animated, audio driven, or MIDI mapped.
Examples
Melted — Iterations 20, Strength 1 on a Box.
Troubleshooting
The mesh shrinks — Laplacian smoothing pulls inward. Follow it with Inflate.
