How can the Background Render Queues history be cleaned up?
In the Background Render Queue you can select some or all of the history items and click the “Remove” button to clear them out. To select everything at once press Ctrl-A (Windows) or Cmd-A (Macintosh). If you don’t see the History panel press the Show History button. Using the Nucleo Support Tool you can choose the Maintenance tab, check the “Render queue control files and history” checkbox and then click the Reset Settings button. This will permanently delete all of the Render Queue information.
