Recently I’ve got a new release with roundtrip-able serializers and JSON/MsgPack support. The return value of this function will be passed to * PostSaveRoot. Usually, it’s enough to simply mark the desired fields with Unreal Engine uses several classes and methods for serialization, built around Unreal's reflection system. The BulkSerialize function is a serialization function that can be used as an alternative operator<< in order to serialize the array as a block of raw bytes, rather than doing per-element serialization.
