Twist


The Twist modifier produces a twirling effect (like wringing out a wet rag) in an object’s geometry. You can control the angle of the twist on any of three axes, and set a bias that compresses the twist effect relative to the pivot point. You can also limit the twist to a section of the geometry.

Twist Param Description

Angle

Determines the amount of twist around the vertical axis.

Bias

Causes the twist rotation to bunch up at either end of the object. When the parameter is negative, the object twists closer to the gizmo center. When the value is positive, the object twists more away from the gizmo center. When the parameter is 0, the twisting is uniform.

Axis

Specify the axis along which the twist will occur. This is the local axis of the Twist gizmo.

Do Region

Limit effect to a region of the mesh.

From

Start of the region.

To

End of the region.
