Stores the index of the current animation per actor in a CrowdFX simulation, where 0 is the first action imported, 1 is the second, and so on. This value is set by Set Pose State ID From Speed in Set Locomotion, or you can use your own logic. If you change this value, make sure to do it in the Simulation region of the Point_Cloud object, before executing any Pose State compounds. In addition, make sure to set Self.__PoseState_ID_Previous for proper blending between animations.
