Currently the way we display normals is always from the PoV of the "body B" from the shape collision pair. This means that either body in that pair can be body B as order is not guaranteed. We will be filing a separate task to improve the UX of normals with respect to this detail.
Cancelling this 2023.2 tech release issue since the support for this release has come to end of life. Cancelling this 2023.2 port case does not affect any LTS or Unity 6 Beta/Preview that remain open.
Reproduction steps:
1. Open the attached "PhysicsSamplesKinematicBug.zip" project
2. Open the "Events - Collisions" Scene ( Assets > 6. Events )
3. Enter the Play mode
4. In the Scene view, observe that the blue arrows on the spheres point upwards
5. Exit the Play mode
6. In the Hierarchy, toggle on the "Events - Collisions Subscene" and expand it
7. Select “Event Surface” GameObject and all the child elements of “Boundary” GameObject
8. In the Inspector, change the Physics Body Components Motion Type property from Static to Kinematic
9. Save the Subscene and toggle it off
10. Enter the Play mode
11. In the Scene view, observe that the blue arrows on spheres point downwards
Expected results: Collision normals remain the same
Actual result: Collision normals get inverted
