Hello, I’ve created a few topics related to an animation problem I’m still meeting and I appologie for this.  
Now based on [this exemple](https://threejs.org/examples/webgl_animation_skinning_additive_blending) I’m trying to make one of my clip additive like so:

`THREE.AnimationUtils.makeClipAdditive(animClip)`

And I’m getting the `Error: THREE.AnimationUtils.makeClipAdditive is not a function`  
What am I doing wrong please?

You have to use at least `r116` in order to use additive animations. What release are you using right now?
