Long time without an update.
I've finally completed the torture droid scene. It's not 100%, as the tracking of the mask is a bit off, so that the cell door appears to wobble a bit, but other than that it is as I intended. NO PROBE! Vader enters and tells Leia that they will discuss the location of the plans, Leia looks towards the door and the door closes.
I will fix the door mask tracking problem later, currently I want to move on to other scenes. I'll post the new video clip soon.
