The Edit DNA Twist Swing node
When to use it
Adds, edits (Set) or removes twist/swing parameter-group setups - the quaternion-driven joint corrective tables RigLogic evaluates - as an ordered list of operations applied atomically.
How to use it
- 1
Wire a DNA in
- 2
Build an ordered list of operations in the Operations panel below the properties
Each entry picks Add / Set / Remove, Twist or Swing, and (Set / Remove) a Setup picked from the per-kind cache below it. Add and a flagged Set need the driver quaternion (exactly 4 raw controls, x/y/z/w), an Axis, and at least one output joint with a blend weight. Set only writes the fields ticked Set Axis / Set Inputs / Set Outputs - an untouched field keeps the setup's current value. Untick an entry to keep it staged without running it.
- 3
Press Apply Twist Swing
Every enabled entry runs in order against the result of every earlier one. The whole batch is atomic: the first refusal publishes nothing at all, not even the operations before it - Summary names the failing entry.
