Maneuvering thrusters not visible in cockpit view

the small slide/roll/reverse thrusters are not being rendered while in cockpit view, which is breaking immersion if parts of the ship that have thrusters on them are visible in said view

This is most easily reproducible with Diaspora's Viper 7. Choose the 2nd to last mission, launch out of the tube and then reverse thrust. If you exit cockpit view and then reverse thrust you will see the effect that should be visible from within the cockpit.
