Twist Op Property Editor

Twists objects, clusters, or tagged points.

To apply: Select them and choose Deform Twist from the Model or Animate toolbar.

To redisplay: Select the object, click the Selection button on the Select panel, then click the Twist Op icon.

Deform

Mute	Toggles the deformation on and off without affecting the values of other parameters.
Twist Active	Applies a gradual rotation about an axis. This parameter is also available on the Twist Effect tab.
Vortex Active	Varies the angle of rotation based on the distance from the axis, creating a swirl effect. This parameter is also available on the Vortex Effect tab.
Axis	The axis of the object's local coordinate space around which the object's points are rotated.
Angle	The total amount of rotation from one end of the object to the other, in degrees. You can type values outside the slider range.

Deformation Center

Use Bounding Box Center	Uses the center of the object's bounding box as the deformation center. If this option is not checked, the object's center is used.
Offset X, Y, Z	Offset of the deformation center from either the bounding box center or the object center in SOFTIMAGE units in the object's local space. You can type values outside the slider range.

Twist Effect

Twist Active

Applies a gradual rotation about an axis. This parameter is also available on the Deform tab.

Angle Modulating Profile

This profile curve controls the fraction of the angle (the vertical axis) over the length of the object (0 to 100% on the horizontal axis). For any point along the length of the object, the degree of rotation is the Angle (set on the Deform tab) multiplied by the corresponding value of this graph. Results greater than 1 produce an exaggerated deformation with a rotation greater than the Angle and negative results produce rotation in the opposite direction. You can edit the profile using the mouse and the same keyboard commands as the animation editor, or right-click to display a menu.

Vortex Effect

Vortex Active

Varies the angle of rotation based on the distance from the axis, creating a swirl effect. This parameter is also available on the Deform tab.

Angle Modulating Radial Profile

This profile curve controls the angle (the vertical axis) over the distance from the axis (0 to 100% in terms of the object's length). For any point along the length of the object, the degree of rotation is the Angle (set on the Deform tab) as modified by the Twist Effect (if on) then multiplied by the corresponding value of this graph. You can edit the profile using the mouse and the same keyboard commands as the animation editor, or right-click to display a menu.
