Determine Reason for Invalid Node Status

  1. Edit file aa, save the changes and wait for the graph to turn purple.
  2. Double-click on cc and in the Node Editor window select the "Why?" tab.
    You will see the reason why FlowTracer thinks that the file cc is not up to date because the transitive input aa has been changed.
    Tip: You can get the same information from the command line with the command vsy.
