This week I mostly wanted to focus on the spine and adding in more breakdowns. As soon as the spine is working everything else off of that gets worked on. The hard thing about this animation, is IK elbows. For this scene, the girl (green character) is IK arms and IK spine, Creasy is IK right arm, FK left arm and IK spine. The reason being that his left arm will never be leaning on the table and i could get better arcs and more fluid movement for dealing with the book. On these rigs the IK arms stretches and it can't be turned off. So this can bring up lots of anti animation to do. Also on this rig is you can lock the IK Elbow in place but when you start moving the hand around it will stretch. SO the whole time you have to make sure and keep an eye out for any strange things. You don't want the character to start with small forearms and by the end of the scene they have grown some what!!!!! That would be bad!!!
For this scene i did a number of tests on what would be the best way to set-up the puppet for the book to change from one hand to another. Constraints would be fine but it can get a bit messy, but i have opted for having two books in the scene. Each hand has a copy of the book which is constrained to the wrist (for different finger placement). So bearing this in mind i had to find a good spot in the animation for the change over to happen and feel very fluid F225 (one book turns off)-F226 (the other books turns on). This is still in the blocking pass so its looking very rough but the change over is there and its working clearly. The key to pulling this off is making sure the placement of the two objects is very similar and making sure the action isn't feeling too forced.
