Kashyyk How to Climb the Roof
After you free all the Wookies, they will tell you that you need to climb the roof. There will be an elevator nearby. Ride it, open the nearest door leading back to the point of meditation. To do this, you have to close the panel using the BD-1. Jump on the pipe at the point of meditation and you will find yourself at a large elevator. Kill the enemy and stand on the white panel in the center of the room.
