Here's the last update before I finish. Just some last minute screen tests. One of the arms and hands are done as well.
Notice the hands. Finger bones for each finger so griping objects looks natural.

The back side of the rib cage is hard to do and to get "just right" so I may save that for an update if I can't bring it together soon.

The neck bones connect and look good but you can't see them from the back....yet. (Note: ask SD to put in the ability to rotate our view in the in game tools so we can see our creations, Sovs, Units, etc, from all angles.)

The tops of the shoulders look a little...odd. Skeletons don't exactly have a lot of "mass" and the model is still 3D with a piece of 2D artwork (the skin) wrapped around it. The top arm part looks fine but the bones where the clavicle should be can't be seen from that angle. I'm worried if I put them in it might complicate the skin too much and make it look less like a skeleton from certain angles. Then again I don't imagine most players will be running around naked. They'll have a shirt or armor of some kind on as will the units they make using this skin.

It's 1 AM now. I'm going to see what I can do in the next few hours to see if I can get some more detail into it. Also as it is now you still have to make the skin color Dark Black for the bones to show properly. Then again maybe you just want a soldier or Sov who has a skull painted on his face in which case it looks cool for that as well. I also have no idea what the offspring of these characters would look like. That should be...interesting heh. I'm not going to spend much longer on version 1.0 so you'll all be able to find out first hand here shortly. I'll put it up by 5 AM so people can download it and start a fresh new game with them tomorrow morning (Saturday) and have Undead in their game for weekend.
Stay tuned...
