===== Notes on rope with Cylinder, Armature, and Spline which is hooked =====


Cylinder - Main Rope
  * Modifier -  Main Rope Armature
  * Subsurf - Viewport=1, Render=2
  * Parent is Main Rope Armature
  * Has Vertex Groups, probably created by the Hook creation menu

Armature - Main Rope Armature
  * Not parented
  * Deform Envelope Distance: 0.208', Envelope Weight: 1.0
  * In Pose Mode, select tip, 
    * Bone Constraint: 
      * Spline IK, 
      * Target Main Rope Curve, 
      * Influence 1
      * Fitting, Chain Length 40
      * Chain Scaling
        * Use Curve Radius (checked)

Curve - Main Rope Curve
  * Not parented
  * Modifier (Hooks, most connect to Empty Objects
    * Falloff
      * Type: Smooth
      * Radius 0

To prevent resizing of armature bones from sliding along curve, on the bone constraint, where we select Spline IK, under Chain Scaling, select Y Scale Mode=None, and XZ Scale Mode=None. (Use Curve Radius is checked, but this might not be important.)
