Blend Graph can trigger ensure Bone.IsRotationNormalized()

Using a custom Blend Graph can trigger the ensure Bone.IsRotationNormalized() when source pose is connected to output.

Open third person template project.

Open the third person animBP

Remove the jump loop state in the default state machine connecting jump start to jump end directly, with transition rule IsInAir?

Set the transition blend logic to custom and connect the source state pose directly to transition blend result.

PIE triggers ensure on the first jump.
