Usage:

1. select a scene level object to be controlled
2. add the controller object from the scene level to the selection
3. press the button to open the Reactive Constraint floating panel
4. Maintain Offset to keep the relative location of the constrained object
5. select axis - X, Y, Z to determine what position aspect will be constrained
6. select axis - Xr, Yr, Zr to determine what rotation aspect will be constrained
7. press Add Constraint to create a constraint on the controlled object

1. select an object that is being constrained
2. press Remove All Constraints to remove all the constraint relationships assigned to the selected item

Controls:

• Maintain Offset - object won't jump the the controlled objects position when the constraint is applied
• X, Y, Z - which axis will be position constrained
• Xr, Yr, Zr - which axis will be rotation constrained
• Use Selection Buttons - instead of pre-selecting objects before, use the buttons below to establish the selections
• Selection Controlled Object - select the constrained object then press this button
• Selection Controller Object - select the object that will do the constraining
• Add Constraint - establish a constraint relationship
• Remove All Constraints - control minimhe original mesh
• Reset - sets the default values for the panel

Reactive Constraint Controls

• X, Y, Z - which axis will be position constrained
• Xr, Yr, Zr - which axis will be rotation constrained
• Weights strength value assigned to each controller object
• Controller node name for the corresponding weight
• Position Offsets position of the constrained object relative to the first controller object attached to it

General Constraint Controls

• active - enables/disables constraint processing.
• Show the same basic controls but without any formatting.
• xFlag, yFlag, zFlag - axis position constrained
• xrFlag, yrFlag, zrFlag - axis rotation constrained
• xOffset, yOffset, zOffset - position offsets
• "pWeight" "pWeight, 1" "pWeight, 2" ... - Weights
• "controller" "controller, 1" "controller, 2" ... - controller node names

Widget based Constraint Controls

• active - enables/disables constraint processing.
• Show the same basic controls but without any formatting.
• xFlag, yFlag, zFlag - not exposed, found inside the "pointConstraint" node
• xrFlag, yrFlag, zrFlag - not exposed, found inside the "rotateConstraint" node
• xOffset, yOffset, zOffset - position offsets
• "Weight" "Weight, 1" "Weight, 2" ... - Weights
• "controller" "controller, 1" "controller, 2" ... - controller node names

• Reactive
  • Only works with scene level items. Does not work with grouped objects.
  • Free axes are available for animation keys.
  • No need to bake animation before rendering
  • Limited to 8 constraints per object.
• General
  • Works with grouped objects.
  • Must bake keyframes before rendering.
  • No limit to the number of constraints.
  • If key frame animation is applied to the controlled(constrained) object then specific key values will need to be deleted.
• Widget Based
  • Works with grouped objects.
  • Use with objects where their matrix values cannot be set directly, like IK handles
  • Must bake keyframes before rendering.
  • 2 subtypes: W Point and W Rotation
  • W Point can be used with IK handles
  • If key frame animation is applied to the controlled(constrained) object then specific key values will need to be deleted.
  • Constraints are driven by widget motion commands instead of setting the matrix directly.
