Description

Snap to Bone doesn't actually affect the rotation of a Constraint in the PhAT editor. The visualizer does show the expected rotation but the Constraint will still rotate in the same direction it was rotated before snapping.

 

Submitted from Bug Submission ID: 386050450

Steps to Reproduce
  1. Open the 3rd Person template project
  2. Open the SK_Mannequin_PhysicsAsset
  3. Select the Constraint foot_l : calf_l
  4. Start and stop simulate to see how the constraint is expected to react
  5. Rotate the Constraint 90 degrees on the Z-axis
  6. Start and stop simulate to see how the constraint reacts
  7. Right-click the constraint in the Graph > Snap to Bone
  8. Start and stop simulate to see how the constraint reacts

Results: Snap to Bone doesn't actually affect the rotation of a Constraint in the PhAT editor. The visualizer does show the expected rotation but the Constraint will still rotate in the same direction it was rotated before the snap.

Expected: For the simulated rotation of the constraint to match the visualization.
