Wind Settings for Soft Cloth

In Character Creator's physics system, each soft-cloth can be assigned individual external forces and wind effects by setting Force and Wind direction and strength.

Force

The Force settings draw the soft-cloth to a given direction while neglecting the global gravity of the project. It is a constant force which may or may not cause wrinkling due to the non-uniform qualities like those exhibited in wind.

  1. Create a project with soft cloth objects (in this case, the character's hair).
  2. Make sure the cloth is selected and go to the Modify > Physics tab.
  3. In the Wind Settings section, set the X, Y and Z values in the Force group (in this case, the [X, Y, Z] = [1000, 0, -500]).
  4. Play back to simulate the soft cloth animation.

    The soft cloth will have a uniform reaction according to the direction of the force assigned.

    ClosedNote:
    • The higher the values are, the stronger the initial force will be.
    • The X, Y and Z directions follow the world axis.

Wind

Unlike the Force setting, the Wind will produce intermittent 'gusts' which simulate the reaction of soft cloth in the wind.

ClosedNote:

Please note that the use of the X, Y and Z axes is the same as described in the previous section.

Gust Frequency

The value of the Gust Frequency determines the number of occurrences of wind gusts in a certain period of time. A higher value dictates that gusts of wind will happen more often and vice versa.

Gust Frequency = 5.0

Gust Frequency = 60.0

Strength

The Strength of the wind for the soft cloth is a range; each gust of wind is generated at a random strength within the range defined by these two sliders.

  1. General Strength: This triangle determines the strength of the basic wind forces. This level also dictates the idle performance of Soft Clothassets.
  2. Gust Strength: This triangle determines the maximum strength of wind gusts.
    • The strength range falls at the weak side (left end) of the slider to generate breeze

    • The strength range falls at the strong side (right end) of the slider to generate strong wind

    • The strength range spans the weak and strong sides (left to right ends) of the slider to generate intermittent gusts of wind.
