Mass, Friction and Damping for Soft Cloth

The properties of a rigid body influence its physics characteristics including colliding behavior, sliding speed, resistance and bounciness behavior.

Mass

Mass influences behaviors when dynamic objects collide. Physics objects with a higher Mass value can cause the ones with a lower Mass value to bounce off more when they bump into each other. In Character Creator, a mass value of 1 equals to 100g.

Please note that the Mass value does not affect the falling speed of physics objects.

Rigid-Body to Soft Cloth

A soft cloth (20) moves toward rigid bodies.

The heavier object (100) stays.

The lighter object (1) is pushed away.

Friction

Friction is the roughness of a surface which generates resistant force and causes a change in speed in objects that slide over it.

Two planes slide down a ramp.

(Ramp's friction = 30)

The plane with higher friction slides slower.

Damping

The Damping value in Character Creator can be taken as air resistance. Each physics object can be applied with individual damping values. The damping produces an opposite-direction force to a physics object's direction of movement, which slows down the speed of the moving object.

The Damping value affects soft cloths tremendously. You can use this value to make a feather or a cloth slowly fall down.

Feathers (soft cloth) with different damping values.

They fall down at different speeds.
