# Sandbox.SkinnedModelRenderer.BoneWorldTransforms

```csharp
System.ReadOnlySpan<Transform> BoneWorldTransforms { get; set; }
```

This frame's final world-space bone transforms, cached so repeated callers - and parallel readers -
share a single skeleton read instead of each fetching bones one at a time. Rebuilt at most once per
frame. The returned data is shared and must not be mutated. Empty if there's no valid model.

Declared in [Sandbox.SkinnedModelRenderer](/api/Sandbox.SkinnedModelRenderer).
Assembly: `Sandbox.Engine`.
