Hi! FastArraySerializer has DeltaSerialize on each array element, but I can’t seem to enable DeltaSerialize within the FFastArraySerializerItem structure itself. Even though it seems like it should work out of the box. I tested it with Unreal Insight, and it makes absolutely no difference whether I change one field in FFastArraySerializerItem or forty… the traffic is the same. Maybe something else needs to be done to make this happen? So that FFastArraySerializerItem actually has DeltaSerialize on each field.
yeah i dont think you can have both, you’re using delta on the array so it only updates the one item, not delta on the item to udpate one field.
likely because FastArrayItems are special and even when changing a field it would need its RepID etc
could be wrong but thats efficient enough
