The older hard coded method has not been removed but will likely be reworked in a future submit. - Now when an editor bulkdata is adding it's payload to the package trailer builder during package save it will poll the virtualization system with a call to the new method ::IsDisabledForObject by passing in it's owner. -- If the owner is valid and was present in the 'DisabledAsset' array then the method will return true and the EPayloadFlags::DisableVirtualization flag will be applied. ### Package Trailer - The pre-existing functionality of enum EPayloadFilter has been moved to a new enum EPayloadStorageType as will only filter payloads based on their storage type. - EPayloadFilter has been modified to filter payloads based on functionality although at the moment the only thing it can filter for is to return payloads that can be virtualized, it is left for future expansion. - EPayloadFlags has been reduced to a uint16 with the remaining 2bytes being turned into a new member EPayloadFilterReason. - This new member allows us to record the exact reason why a payload is excluded from virtualization. If it is zero then the payload can virtualize, otherwise it will contain one or more reasons as to why it is being excluded. For this reason the enum is a bitfield. - Added overloads of ::GetPayloads and ::GetNumPayloads that take EPayloadFilter rather than a EPayloadStorageType - Added wrappers around all AccessMode types for FLookupTableEntry. - FPackageTrailerBuilder has been extended to take a EPayloadFilterReason so that the caller can already provide a reason why the payload cannot be virtualized. -- As a future peace of work this will probably be changed and we will ask the caller to pass in the owner UObject pointer instead and then we will process the filtering when building the package trailer to a) keep all of the filtering code in one place b) keep the filtering consistent ### PackageSubmissionChecks - The virtualization process in will now request the payloads that can be virtualized from the package trailer, which respects the new payload flag, rather than requesting all locally stored payloads. ### UObjects - There is no need for the SoundWave or MeshDescription classes to opt out of virtualization on construction. This will be done when the package is saved and is now data driven rather than being hardcoded. ### DumpPackagePayloadInfo - The command has been updated to also display the filter reasons applied to each payload [CL 20240971 by paul chipchase in ue5-main branch]
