Syntax

virtual bool BatchUpdateInstancesTransforms
(
    int32 StartInstanceIndex,
    const TArray< FTransform > & NewInstancesTransforms,
    bool bWorldSpace,
    bool bMarkRenderStateDirty,
    bool bTeleport
)

Remarks

Update the transform for an array of instances.

Returns

True on success.

Parameters

Parameter	Description
StartInstanceIndex	The starting index of the instances to update
NewInstancesTransforms	The new transforms
bWorldSpace	If true, the new transforms are 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).
