Steps to Reproduce

Demo video: https://youtu.be/Iz2ASgFisZ8

  • Create a control rig and import manny skeleton as an example
  • Add a construction event node add spawn a root transform control
  • From the root transform control, drag the output rig element key to make a spawn animation channel node
  • Resolve the variable type for the input pins on the animation channel node
  • Compile and see no channels show up

Expected Result

  • Channels are resolved and shown when execution pin is attached

Observed Result

  • There is an execute context connection but it’s transparent and also not actually connected
  • Reconnecting shows the newly created animation channel
  • Closing and reopening the control rig repaints the graph editor showing that the connection was actually broken
