Blueprint: “Orrery Terrain Net Hello”, a Blueprint type

Name	Type	Default	Meaning
`NetVersion`BlueprintReadOnly	`int32`	`0`	—
`SculptRecordVersion`BlueprintReadOnly	`int32`	`0`	—
`SaveVersion`BlueprintReadOnly	`int32`	`0`	—
`NaturalHash`BlueprintReadOnly	`int64`	`0`	The natural ground's content hash (ITileSource::ContentHash): the ground never travels.
`GridHash`BlueprintReadOnly	`int64`	`0`	The grid's identity: origin, post spacing, edit subdivision.
`HeldMasks`BlueprintReadOnly	`TArray<int64>`	—	The brush masks this side holds already (their ids, ascending; up to 1,024, net version 5): the server sends their BrushMask records as the hash only and leaves them out of the join's mask frames. A resync's Hello refreshes it.
`CachedSaveHash`BlueprintReadOnly	`int64`	`0`	The file hash of the terrain save this client kept from an earlier join (net version 6); 0 when it holds none. The server then sends only what that save does not hold. The client checks every byte it takes from it against the join's hashes.
