Week 6/8 - Rigging and skinning

22 November 2019

Rigging is the setting of the skeleton and controls, whilst skinning binds the mesh together. Joints are connected by bones, it visually represent how the joints are connected together in hierarchy. The hierarchy joins together all the bones and joints into one skeleton, the HIP joints controls everything such as being able to rotate and move.

There are IK and FK, IK (inverse kinematics) IK work independently and good for sticking feet on the ground. Or the IK could be the child, effect the movement of its parent. and FK is the parent moving the child. Each node represent a controller, it can be switched from FK and IK which is called HumanIK. Human IK have all names ready in the hierarchy, this it the rigging I will be using for this brief.

WORKSHOP

EXERCISE 1: JOINTS AND BONES

Create a cylinder.
Position a Bone Chain inside consisting of two bones and one joint to make a leg with a 'knee'. (in Rigging > Skeleton > create Joints)
Use the Move Tool to adjust the position of joints (Poisting Upper, middle and bottom)
Bind the cylinder mesh to the bones. (Selected cylinder and bone > Skin > Bind Skin)
Rotate the bones to see the effect on the deformation of the cylinder.

EXERCISE 2: IK CHAIN

Following on from exercise 1:

From the Rigging menu, select the Insert IK Chain command. (Skeleton > IK Handle)
Following the melscript prompt (the script line at the bottom of your maya interface), click on the first joint and then the last joint in the chain.
Watch what happens. (Select top and bottom joint)
Use the MOVE manipulator to select and move the IK Chain noting the behaviour of the joint.
