- Revive UMetaSound Asset type - Revive MS Output generation - Fix copy pasta'ed type name so MetaSound Source shows up properly in editor - Clean-up to dynamic doc version reporting if required (show the new version number in log) - Add versioning to update the RootGraphClass name & add DisplayName MetaSound Registry Scaffolding Part 1 (From Phil Popp) #rb phil.popp #jira UE-117108 #jira UE-117109 #jira UE-117110 #preflight 60bf11780c76f90001db5f5f #ROBOMERGE-SOURCE: CL 16587155 #ROBOMERGE-BOT: (v828-16531559) [CL 16587204 by rob gay in ue5-main branch]
