Wind Force

The wind force directionally accelerates or decelerate the speed of dynamic items in a scene until the velocities match that of the wind force.

You can add a wind force item to a simulation by selecting Forces > Wind in the Layout interface's toolbox. Alternatively, in the Items list, click Add Item > Forces > Wind Force. Any force added after a dynamic body auto-connects to the solver item, forces added beforehand need to be connected manually in the Schematic view.

Remove force items the same way as any other item: simply select the item and press Delete on the keyboard.

When selected, the following attributes appear in the Properties viewport.

Mesh Dynamics Panel

Option

Description

Name

Displays the current force item name. To change it, click on the field and type in the new name.

Transform

Position X/Y/Z

The wind force item globally affects dynamic items regardless of its position, therefore these values don't influence the force's effect.

Rotation X/Y/Z

Rotation values affect the direction of the wind force options, allowing you to easily change the direction of the force applied to dynamic items. Default forward direction is Y+.

Scale X/Y/Z

The wind force item globally affects dynamic items, regardless of its scale, therefore these values are not applicable to it.

Wind Force

Enable

Toggles the force item on or off. When enabled, the force item is considered during a dynamics simulation; when disabled, the force item is ignored. However, disabled forces are persistent across Modo sessions, being saved with the scene, and retain their present settings.

Invert

Reverses the directional values of the wind.

Strength

Determines how much influence the wind force has on the dynamic items. The higher the value the greater the push of the wind.

Torque

Determines how much influence the wind force has on the dynamic items. The higher the value the greater the push of the wind.

Velocity

The speed of the wind force. Dynamic items affected by this force don't move faster than the defined value (unless they have their own additional forces or impulses controlling them).

Inherit Velocity

Controls the degree to which the motions of the wind force locator itself affect the wind movement.

Speed

Determines the actual speed at which the force moves or affects its target items.
