virtual bool BatchUpdateInstancesTransforms

int32 StartInstanceIndex,

Remarks
Update the transform for an array of instances. True on success.
Parameters
| Name | 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). |
