In the making of the CG phantom, I'm stuck looking at the resin kit arms.
The way they're done doesn't see to able all the human movement, particularly the front arm rotation (front arm is made of 2 bones, so it can rotate at about 160° I think), on the kit, the front arm is made of only one "bone", with several "power cylinder" mounted on it, so it can't turn that much, or the power cylinder would twist and break

There's also a problem with the shoulder rotation. On the kit, the arm armor hasn't enough place to rotate in the big shoulder armor. I can correct that in 3D, but the joint is weird anyway, my guess is that all the shoulder power cylinder (3 on the kit) work together to orientate the arm. There's not much place in it, but there's the shoulder armor, so if everything intersects when it moves, I won't care much as long as it's not visible


If you look at smokewalls, he cheated a bit as the bende arm has
But before I think of how to change that so it can move, I need a bit more knowledge about the power cylinder system.
Does it works like some pneumatic jack ? Just with another energy ? (btw, what flows in the by-pass cables ?)
Or is it something more complex ?
Is it all metal ? Or may there be some mysterious hard material that can bend anyway ?
