# MeshResource.JointInfluences

A buffer of vertex-joint influences which bind the mesh part’s vertices to a skeleton via a
skinning deformation.

```
struct JointInfluences
```

## Overview

Each vertex is associated with a fixed number of influences. If `influencesPerVertex` is 4,
then there should be four elements in the buffer of joint influences for each vertex in the
mesh part.

> Note: If a particular vertex needs fewer influences than the `influencesPerVertex` value,
> the influences for that vertex can be padded with zero-weight influences.

## Topics

### Initializers

[`init(influences: MeshBuffers.JointInfluences, influencesPerVertex: Int)`](/documentation/RealityKit/MeshResource/JointInfluences/init(influences:influencesPerVertex:))

Associates every vertex in the mesh with a fixed number of influences per vertex.

### Instance Properties

[`var influences: MeshBuffers.JointInfluences`](/documentation/RealityKit/MeshResource/JointInfluences/influences)

Buffer of joint influences.
