# MeshResource.JointInfluences

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

## Declaration

```swift
struct JointInfluences
```

## Overview

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.
