Hi Paul, The OSG doesn't have an observer system for matrix transforms, so you can't watch something and get informed of changes to it.
To find out whether the inherited matrices have changed you'll either need to cache their values yourself, or cache the result of getWorldMatrices() and use a delta in this to determine if it's changed.
