Class Smoothing
Utilities for working with smoothing groups. Smoothing groups are how ProBuilder defines hard and soft edges. ProBuilder calculates vertex normals by first calculating the normal for every face, which in turn is applied to each vertex that makes up the face. Afterwards, each vertex normal is averaged with coincident vertices belonging to the same smoothing group.

Syntax
public static class SmoothingMethods
ApplySmoothingGroups(ProBuilderMesh, IEnumerable<Face>, Single)
Generate smoothing groups for a set of faces by comparing adjacent faces with normal differences less than angleThreshold (in degrees).
Declaration
public static void ApplySmoothingGroups(ProBuilderMesh mesh, IEnumerable<Face> faces, float angleThreshold)Parameters
| Type | Name | Description |
|---|---|---|
| ProBuilderMesh | mesh | The source mesh. |
| System.Collections.Generic.IEnumerable<Face> | faces | Faces to be considered for smoothing. |
| System.Single | angleThreshold | The maximum angle difference in degrees between adjacent face normals for the shared edge to be considered smooth. |
GetUnusedSmoothingGroup(ProBuilderMesh)
Get the first available unused smoothing group.
Declaration
public static int GetUnusedSmoothingGroup(ProBuilderMesh mesh)Parameters
| Type | Name | Description |
|---|---|---|
| ProBuilderMesh | mesh | The target mesh. |
Returns
| Type | Description |
|---|---|
| System.Int32 | An unused smoothing group. |
IsSmooth(Int32)
Is the smooth group value considered smooth?
Declaration
public static bool IsSmooth(int index)Parameters
| Type | Name | Description |
|---|---|---|
| System.Int32 | index | The smoothing group to test. |
Returns
| Type | Description |
|---|---|
| System.Boolean | True if the smoothing group value is smoothed, false if not. |
