Rigging

• 
  
  Kinematics:

  Kinematics can be defined as Bone Engineering

  • Forward Kinematics (FK) – Used mainly for Rotation based animation.
  • Inward Kinematics (IK) – Used mainly for Movement based animation.
  Tool Used: Joint Tool (in Animation Tab)
  
  Few Important Notes:
  • Joints/Bones are always in Parent – Child Relationship.
  • IK
  • Joints stay of the actual length but IK can stretch
  • Grab the IK controller & not the bone for movement.
  • Make sure that there’s a little bend in the bones while drawing for IK
  • Press & hold D to change the size & bend relative to the other joints.
    

  Skin Binding:
  
  Steps:
  • Select Joints.
  • Select the Object (Eg : Cylinder with sub-divisions)
  • Goto Menu Skin (in Animation Section) – Bind Skin – Smooth Bind

  IMP: In Hand Rig, the main joint is the Elbow Joint.
  

  Exercise 1:

  Create a simple Box Model of Hand. Create Parent – Child Relationship & setup a simple Joint.

  
  IMP:

  • P is used for Parenting
  • Always Select Child First & then the Parent Object for Parenting.
  • Pivot is Moved to the Edge of the object for Correct Rotation of Hand.
