- Move bIsDefault/bCanEdit(renamed bIsModifiable) from InterfaceRegistryEntry to Interface data definition - Add checks in builder to disallow mutation of interfaces that shouldn't be via editor or document builder (ex. SourceInterface which is default and then never changed) - Optimize SearchEngine query for finding default interfaces - Tweak MetaSoundUObjectRegistry to support non MetasoundAssetBase classes and add UMetaSoundBuilderDocument. Update iterator w/optional param to only return asset types (true by default for back compat) - Move FName class name comparitors to use new TopLevelAssetPath #rb phil.popp #jira UE-181360 #rnx #p4v-preflight-copy 24658328 #preflight 642b10834d26bcd1eb0e566c [CL 24920763 by rob gay in ue5-main branch]
