Please see Babylon.js Playground A larger number of steps seems to make the simulation more magnetic. Is that the desired behavior?

I think the issue @maz and I are seeing is that restitution (bounciness of ball when hitting ground) is dependent on the subTimeStep. A smaller subTimeStep seems to cause the ball to be less bouncy (when passing true to new BABYLON.<Ammo/Cannon>JSPlugin(true)) I’ve been trying to look into this: R…

so it might well be a bug on their side ??? if I understand correctly ?

Ah, I’m not familiar with the mathematics behind restitution. Maybe the physics libraries we depend on don’t maintain the same level of bounciness with changing subTimeStep? For reference, here is a PG where uncommenting one line will change the bounciness of the ball [image] Babylon.js P…

You can see a great explanation from Cedric here: Physics: should setSubTimeStep speed up simulation?
