#rb Per.Larsson, Devin.Doucette #jira UE-133497 #rnx #preflight 61f835491c5ac5523462810a - A lot of files have been touched but most of this is changing FPayload::IsValid to !FIoHash::IsZero, the main changes are in EditorBulkData/EditorBulkDataTests - The only difference between FPayloadId and FIoHash is that the former considered the hash of an invalid or empty buffer to be 'invalid' too where as FIoHash would return a valid hash -- To keep behaviour the same, we only hash payloads in EditorBulkData using a utility method ::HashBuffer which will not hash empty or invalid payloads and return a default FIoHash instead. -- Unit tests have been extended to prove that the behaviour has not changed. #ROBOMERGE-AUTHOR: paul.chipchase #ROBOMERGE-SOURCE: CL 18806362 in //UE5/Release-5.0/... via CL 18808527 via CL 18821790 #ROBOMERGE-BOT: UE5 (Release-Engine-Test -> Main) (v908-18788545) [CL 18822154 by paul chipchase in ue5-main branch]
