Its the Ma'At you're thinking of. I know one that might fit the bill for Bob's needs. You may remember back before the great blackout, someone was showing off a smooth freighter that was kinda based on the Poseiodon, but with 4 arms. Most people commented that it looked like a giant sloth, because the bottom end of each arm had a wrist joint that wraped around the bottom of the container, but it resembled the way that the giant sloth walks on its outer palms and wrists to keep their claws strong and sharp.
While we're considering it Bob, I've got a question regarding this model animation system. When it was first introduced, the Star Wars Conversion team was wanting to find a way to get it to work for S-Foils so that the firepoints would change location but become locked when the S-Foils go from "X" to compact. I understand you got around that by having another pair of invisible, locked, firepoints lined up for the closed wings. Here's were things change. Could we have a dockpoint that moves? Example, a Deimos approaches a station and docks with it, but instead of the ship having to make contact with the hull of the station an arm swings out (or extends if you can get translations working) with the dockpoint on the end. The Deimos would then dock to this docking arm. The extension/retraction of the arm would likely have to be scripted for sequences, since the arm would be unlikely to swing out automatically. As it is right now, an order for Ship A to dock with Ship B will do nothing with the AI of Ship B without scripting.
Later!
