One recommendation I have in hindsight is instead of copying the expression in the transform of the Noise TOPs around is to place that expression into a Constant CHOP, attach a Null to the constant and pass a reference from that Null in your components. This will let you modify that expression in 1 place instead of having to go into each component and modify it.
