Default

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


Atomic

The `Class.Model` and all of its descendants are streamed in/out together.
For streaming in, this applies when **any** descendant `Class.BasePart` is
eligible for streaming in. For streaming out, this applies when **all**
descendant `Class.BasePart|BaseParts` are eligible for streaming out.


Persistent

Persistent models are sent as a complete atomic unit soon after the player
joins and before the `Class.Workspace.PersistentLoaded` event fires.
Persistent models and their descendants are never streamed out.


PersistentPerPlayer

Behaves as a persistent model for players that have been added using
`Class.Model:AddPersistentPlayer()`. For other players, behavior is the
same as **Atomic**. You can revert a model from player persistence via
`Class.Model:RemovePersistentPlayer()`.


Nonatomic

When a nonatomic model is streamed, descendants are also sent, except for
part descendants. Nonatomic models that are not descendants of parts are
sent during experience loading.


ModelStreamingMode

Controls stream in and out behavior of a model.

Default Value: {defaultValueStart}{defaultValueEnd}

This function returns immediately if possible, but can yield the thread that called it until it can return a value.

This member doesn’t appear in the object browser and is not intended for widespread use.

This member is only accessible only through the command bar. Attempting to access this member from scripts causes an error.

This function can’t pause the Lua thread that called it.

Attempting to access this member in scripts causes an error. You might be able to access this member from Roblox Studio's property window.

This member doesn’t appear in Roblox Studio’s Object Browser.

You can’t create an instance of this class with the Instance.new constructor.

Roblox does not replicate this member across its server-client boundary.

Lua code can’t access this member. You might be able to change its value from the property window in Roblox Studio.

This object’s replication behavior is dependent on the player who owns it.

This member is accessible only through the command bar and plugins only. Attempting to access this member from scripts causes an error.

This property is read-only and is safe to read in unsynchronized threads. Attempting to write to it causes an error.

This member is read only. Attempting to write to this member causes an error.

This member is accessible only in CoreScripts.

Only Roblox CoreScripts can access this member, and it isn’t usable by Players.

You can read and write to this property safely from multiple threads.

This class is a top-level singleton. Retrieve an instance of this class with the GetService function.

Multiple threads can potentially write to this property, so it’s unsafe to read from unsynchronized threads.

This function pauses the Lua thread that called it until it returns a result. This doesn’t interrupt other scripts.
