Gravity acceleration is different for different mass Screenshot at 2020-02-16 20-20-40 make some spheres with mass=5.0 and cubes with mass=0.1f with near the same coordinates and they fall to ground with different velocity(acceleration)

jhwangbo commented 4 years ago

do you use linear damping?

geotyper commented 4 years ago

yes, use linear damping=0.55

jhwangbo commented 4 years ago

If you use linear damping, they are not guaranteed to accelerate at the same rate. Think about a ball falling in the water

This does not seem like a simulation issue. Closing it for now
