- Track Instance Inputs can now be used as capture sources to capture pre-animated state - PreAnimatedState extension now simply exists as a member of UMovieSceneEntitySystem. Previously the existence of the extension was used to determine whether any pre-animated state logic was required, but in practice this created more problems than it solved and led to some convoluted lifetime management code. - Added a templated group manager type from which the object group manager can inherit. This simplifies the introduction of new group managers - Removed the requirement that all pre-animated state must exist as part of a valid group. This forced state from 'master' tracks to be arbitrarily grouped together which put an unnecessary burden on the storage classes. #jira UE-132512 #rb max.chen, matt.hoffman [FYI] andrew.rodham #preflight 61f2ca893765218cf01f290e #ROBOMERGE-AUTHOR: max.chen #ROBOMERGE-SOURCE: CL 18754810 in //UE5/Release-5.0/... via CL 18754825 via CL 18757520 #ROBOMERGE-BOT: UE5 (Release-Engine-Test -> Main) (v903-18687472) [CL 18758489 by max chen in ue5-main branch]
