Returns

True on success.

Parameters

Parameter	Description
StartInstanceIndex	The starting index of the instances to update
NumInstances	The number of instances to update
NewInstancesTransform	The new transform
bWorldSpace	If true, the new transform is interpreted as a World Space transform, otherwise it is interpreted as Local Space
bMarkRenderStateDirty	If true, the change should be visible immediately. If you are updating many instances you should only set this to true for the last instance.
bTeleport	Whether or not the instances physics should be moved normally, or teleported (moved instantly, ignoring velocity).
