Here is the finished piece, for reference.
So you'll notice that each Eudimorphodon is in a different and unique pose from the others.
Lucky for me there is pretty powerful weapon in my 3D arsenal that was going to make things easier. A 3D "skeleton" rig...
Before I jump into the complex problem that was a Pterosaur wing, I'll give you the quick 101 on rigging (I personally have only just graduated to the 200 or 300 level... I'm aiming to enter my post grad level by this time next year :P).
Let's say I build this nice Dinosaur leg... funny enough I actually did, come to think of it ;)... The leg itself and the individual toes are all solid pieces. Apart from where the back end of the toes meet the ankle there no inherent joints in this model. Meaning as is there is no way for me to pose anything other than which way the toes will be pointing from the ankle.
Lastly my detailing doesn't move with the resculpting. So all the individually modelled toe scales don't follow or reorient with the leg and toes when I repose them. Meaning I have to go in and manually reposition each and every single one of them back onto the leg and toes...
The other big setback is that rigging a model eats up a lot of computing power and memory. So not only does it take longer to do things within the program, but your model tends to triple in file size.
Despite these inconveniences they make posing animal models SO much easier in the long run!
Skeletal rigs take care of all the problems I mentioned before.
The first and foremost is the ease of bending the model. Resculpting each piece takes forever! Plus if you don't get it right you have to start all over again... With the skeleton you can create a new pose within a few seconds!
In the end I had a pretty good "simple" rig that allowed me pretty good fluid control on my Pterosaur. I say simple in its use. I only have 5 major points (outside of posing the toes) to worry about.
It wasn't perfect (as none of my 3D skeletoning jobs are... remember I'm only a beginner to intermediate in their use so far). I couldn't bend the legs too much or the tenting would come back along the back edge of the wing. I also found that if I curled the inside toes to much a really weird tug line would appear all the way from the toe up to the chest...
Despite all this, and the mediocre piece it produced, I did learn a TON about my program's 3D rigging!
As a very quick aside, the inside joke of the photo these Pterosaurs are flying over is that they are fishing over top of some petrified trees. This is a photo of a famous petrified forest here in New Zealand.
There is a long fallen fossil log running between the far left Pterosaurs, a circular tree stump just above the bottom Pterosaur's left wing tip, and another circular stump in between the top two Pterosaurs in the upper middle.
