int
The instance ID of the GameObject to create additional instances of.

count

int
The number of instances of the GameObject to create.

newInstanceIDs

NativeArray<int>
Pre-allocated NativeArray to populate with the instance IDs of the new GameObjects. Must be the same size as 
count
.

newTransformInstanceIDs

NativeArray<int>
Pre-allocated NativeArray to populate with the instance IDs of the Transforms of the new GameObjects. Must be the same size as 
count
.

destinationScene

Scene
