This case creates conditions that require tweaking the ccd threshold parameter in the physics engine, which we unfortunately can not expose in this LTS stream.
Reproduction steps:
1. Open the attached “FalsePositiveCollision_Ramp.zip” project
2. Open the "FalsePositiveCollision_Ramp" Scene ( Assets > Tests > GameFeel )
3. Select the "GameFeel_Ball_GolfBall_Primative" prefab
4. Find the Rigidbody Component in the Inspector Window and set Collision Detection to "Continous" or "Continous Dynamic"
5. Enter the Play mode
6. Observe the movement of the prefabs
Expected results: All of the prefabs slide up the "Ramp" object
Actual results: Half of the prefabs fly off upwards
