Engine determines best behavior. Currently equivalent to **Legacy**.


Legacy

Models are sent when their parent is sent, typically during player join.
Models are never streamed out unless an ancestor of the model is streamed
out.


Improved

Models are never sent during player join. Models that are "non-spatial"
(containing no `Class.BasePart` descendants) are sent soon after join, but
before the `Class.Workspace.PersistentLoaded` event fires. Models that are
"spatial" (containing `Class.BasePart` descendants) are sent when any
`Class.BasePart` descendant needs to be streamed to a client, and may
stream out when all `Class.BasePart` descendants are eligible to stream
out.


ModelStreamingBehavior

/reference/engine/enums/ModelStreamingBehavior.yaml

Controls how `Class.Model|Models` are sent to clients in experiences with
instance streaming enabled.
