Parameter

Define the amount of friction experienced by particles.

Friction [-∞..+∞]

Defines the strength of friction that resists the movement of the particles. Higher values slow down the particles more rapidly.

Spin Friction [-∞..+∞]

Spin Friction slows down the spin of the particles. The higher the value, the less time it takes until the particles stop spinning.

Mass Dependence [-100..100%]

The friction will be calculated according to the mass of the particles. The higher the value, the more influence the mass has on the friction; particles with a high mass will be less affected by the friction than those with a low mass. This approximates the natural behavior of friction.

Size Dependence [-100..100%]

The friction will be calculated according to the particle size; the higher the value, the more influence the particle size has on the friction. Large particles will be slowed down more quickly than smaller ones.

Friction slows down particles to give real-world effects. Here we are changing the friction over time by connecting a Time node to the Friction port. So particles will slow down more and more over time.

Additional input ports:

• On

A Boole value of True switches the node on; a value of False switches it off.

• Animation Time

Since the node’s parameters can be keyframe animated, by default the Cinema 4D time is used internally to ensure that the values are interpolated correctly. However, you can pass your own time value to this port. This should be of the data type Time, which is a Real number in the simplest case. If no value is passed, Cinema 4D’s time is used.

• Particle

Connect this port to the stream of particles to which the friction should be applied, such as to the Particle output port of a PPass node.
