I know this is a very specific case but if you are working on a 2d sidescroller and are having trouble with gravity and linear dampening. Set linear dampening to the defualt and after a set delay or when they reach the ground set it to 40.
How is this situation nowadays? Any progress made to make it easier to make it lose energy? I’m using PCM and i still have issues in 4.17.
As far as I know this still is and will remain an issue. Have to develop custom fixes for specific use cases 
Greetings from 2024. I’m wondering if we have figured out how to make a rolling ball stop after Add Impulse at Location?
EDIT
Upping the Linear / Angular Damping seems to do the trick and the sphere comes to a complete stop.
Chaos is different.
And even before that the physics friction calculations would only be applied based on the tick/physics tick.
Basically if you just do the calculations yourself you can be sure of the results since they arent frame or compute dependent.
Everything else is always going to go random to some extent, mostly because of the inaccuracies that take place between each frame’s calculation…
Will the ball stop on its own? Not with the default chaos settings.
The physics objects keep pulsating/moving and not going to sleep.
If you figure out the sleep settings you have somewhat of a chance to get it to actually stops…
