### Remarks

To successfully use this method, [AnimationMode.BeginSampling](/engine/6000.0/script-reference/unityeditor/animationmode/beginsampling.md) must be called before this method and [AnimationMode.EndSampling](/engine/6000.0/script-reference/unityeditor/animationmode/endsampling.md) must be called after. If a property is no longer sampled (for example, through [AnimationMode.SampleAnimationClip](/engine/6000.0/script-reference/unityeditor/animationmode/sampleanimationclip.md), [AnimationMode.SamplePlayableGraph](/engine/6000.0/script-reference/unityeditor/animationmode/sampleplayablegraph.md), or [AnimationMode.AddPropertyModification](/engine/6000.0/script-reference/unityeditor/animationmode/addpropertymodification.md)), the property reverts to its original value when [AnimationMode.EndSampling](/engine/6000.0/script-reference/unityeditor/animationmode/endsampling.md) is called.
