Spline IK Management

• Stability

  • Bones derive orientation from curve tangent
  • Control tangents by grouping CV's
    • Group should include at least 4 cv's
    • Control groups should be larger than bones they control
    • Scaling control groups increases tightness of the spline

• Popping

  • When curve is too short for bone chain
  • Prevent pops by extending control curve

• Snapping

  • Occurs when curve is too tight
  • Minimize by limiting the number of Cvs
  • In Maya, try smoothCurve with history
