Running into a physics issue in 4.16 (tested in 4.15 and 4.14 and is not present). I created and ran the roller template and noticed the ball never comes to a rest. It seems to be an issue with sphere collision.
Please see the attached video for an example. Example Video
Seems replacing the sphere collision on the ball with a capsule collision shape works fine (with it’s cylinder height reduced so it’s rounded ends are next to one another and it looks spherical).
