A dynamic object always needs a certain amount of mass to become influenced by forces. In RealFlow, mass is always given in kilograms and the initial value is calculated automatically. Actually, the “Density” parameter from the “Soft body” panel has exactly the same mode of operation and functionality as its counterpart in “Rigid body”. Density is defined as mass per volume unit [kg/m3].
Resolution
Higher settings create a more detailed simulation of the soft body, but also need longer calculation time. The idea behind this parameter is to make the body react much more accurately with more deformations. All in all, “Resolution” strongly enhances a simulation’s realism. This value can be raised to a (virtually) infinite level.

Sometimes you do not want a simulation to start from zero, but the objects should have some initial velocity. With this parameter you can assign such a behaviour by simply entering positive or negative values. Please keep in mind that “@ Velocity” directly determines the body’s trajectory. A value of [ 2,0,0 ], for example, creates a linear motion along the positive X axis. The unit is metres per second [m/s].
@ Rotation W
This parameter actually works the same way as @ Velocity. Instead of an initial velocity, you can add an initial rotation and it is mostly used to avoid a uniform look. You also have three values and each one is measured in degrees per second [deg/s]. Negative angles are also accepted.
