A MultiBody can consist of several objects, but it is not possible to change the objects' masses individually. Therefore, mass is controlled indirectly via this parameter: density = mass / volume.

Internal resolution
Soft bodies use a voxelization method in order to bend polygons correctly. Imagine an object, where the triangles are bigger than the voxels. In such a case it is likely that the simulation will turn out wrong.

This is the amount of resistance caused by a surrounding atmosphere. High settings can stop an object completely.

damping
With high values, a body stops bouncing very fast and it will experience smaller bounces. You can use settings between 0.0 and infinity: a value of 0.5 will stop the entire internal movement after 2 seconds, a value of 1, after 1 second, for example.
