Friday the 13th Class


Reverse Foot Rig

The reverse foot rig does exactly as the name suggests. Using a joint chain that runs up the leg and IK solvers you create a leg rig that allow you to pivot from the toe, ball of foot, heel, and ankle. This is very useful so that a character can have steady feet.

IK Spline Spine

IK spline is a type of solver that positions joints along a curve. This is particularly useful for the spine since it acts much like a curve.

FK Controllers

FK controllers allow the animator work in a forward manner. This is useful for a variety of situations such as the arms.

Set Driven Key Hands

Set driven keys allow you to record attribute values much like animation keys but instead of being tied to the timeline they are tied to other attribute values. For example, You can create attributes for each finger in a hand, then record the joint rotations of the finger joints at different values for those attributes.

Other Rigging

Let’s finish up other missing rigging elements such as the eye rigging.

Blend Shapes

Blend Shapes:

Blend Shapes: Blend shape deformers let you change the shape of one object into the shapes of other objects. Blend shapes do exactly what the name suggests. (in other software these are often referred to morphs or morph targets)

Blend shapes can be use for all sort of things:

  • Transform one object into another (swan to a princess [difficult])
  • Fix particular shapes (push the butt out when leg goes back)
  • Use for simple animation (open/closed drawer)
  • Add extra deformations (you could place a non-linear wave deformer on to a blend shape)
  • Most common for facial animation (make all of your targets for a character’s face)
  • All sorts of things YOU haven’t come up with (the sky is always the limit; fie on you sky!)

Facial Blend Shapes:

Blend shapes are still the preferred method for rigging the face.

Class 13: Rig & Animation (FK rigging) Lab

Rig & Animation (FK rigging) Lab

Forward kinematics (FK) is the default way that joints work. Just a basic heirarchy. However, you never want to animate on the skeleton directly. This means that controllers should be created to interact with. Once those are produce any remaining rigging elements will be developed.

You will be graded on the following:
  • Lab Requirements
    • Techniques and processes covered in the instructional material is followed and implemented.
  • Creativity & Craftsmanship
    • Excellent design choices, novel & appealing, and solid clean caliber work.
