# boneInverseBindTransforms

The default transforms for the animation skeleton’s bone nodes.

## Declaration

```swift
var boneInverseBindTransforms: [NSValue]? { get }
```

## Discussion

Discussion An array of NSValue objects containing SCNMatrix4 transforms, each of which corresponds to a node in the bones array. Each value is the inverse of the bone node’s transform from bind space (that is, of the concatenation of all transforms from the skeleton root down to that bone) in the skeleton’s default pose.
