Fieldwork: Arms

• Arm rig choice should be simple:

  • FK for expression
  • IK for directional movements

• ... but it's not.

• Arm rigs are more complex than legs

  • Control and pole vectors may be in several spaces
    • World
    • Body
    • Object specific

• Arms often need complex control switching

  • FK > IK
  • Different IK spaces
  • Active and passive

• Arm rigs benefit a lot from forethought

  • Multiple rigs for multiple scenarios
  • Balance setup costs against counteranimation costs
