unity version : 2017.2.1p2
slate version : 1.8.0f1
Assets/ParadoxNotion/SLATE Cinematic Sequencer/Directables/Tracks/Runtime/Actor/AnimatorTrack_2017.cs(205,16): error CS1061: Type UnityEngine.Animations.AnimationLayerMixerPlayable' does not contain a definition forPause’ and no extension method Pause' of typeUnityEngine.Animations.AnimationLayerMixerPlayable’ could be found. Are you missing an assembly reference?
I am sorry, but Unity is changing the Playables API pretty much in every dot update and is impossible to support all dot version due to the vast amount of changes Unity does.
Slate supports Unity v5.6, and any version of Unity v2017.3+ and above.
Is it possible to please update to Unity v2017.3+ in your project? The problem will then be solved.
