| graph | The PlayableGraph to sample. |
| index | The output index to sample in the Playable Graph. |
| time | The time at which to sample. |
Samples the specified output index of a PlayableGraph and also records modified properties when in Animation mode.
To successfully use this method, BeginSampling must be called before this method and EndSampling must be called after. If a property is no longer sampled (for example, through SampleAnimationClip, SamplePlayableGraph, or AddPropertyModification), the property reverts to its original value when EndSampling is called.
