I did a test of how the arm could work, I used a spline IK and a lattice to create this quick test. It seems to be working alright for what I need and the set up is pretty simple. I will move onto creating the actual arm next and then add it all to the previs!
I did some designs for the arm/hand that will be attacking the boy. I wanted it to feel more like a blanket and more cloth like. I think number 3 - 5 are working for me, its thin side on and had buttons where the knuckles are to attach the fingers. being thin it should wrap around the boy nicely!
I made a few tweaks and did a test animation of the mouth in flash for the sighing scene, it proved slightly difficult to start with but I quickly got the hang of it and overall I think it added a lot of life to the sigh.
