UpdateInstancesData recreates the instances data buffer from the array of WorldColorInstanceData that was set by calling the SetInstancesData(WorldColorInstanceData) method.
When the BoundingBox has changed and you know the new bounding box, call the UpdateInstancesData(BoundingBox) to prevent calculating it from the instances data.
