Axial deformer is a modifier that translates target points based on their distance or projection to the defined axis. The level of deformation can be controlled with three parameters: Angle, that controls the rotation about the axis (tangential translation), Scale controlling how much point is scaled about the axis and Translation that defines how much points are moved along the axis. Control curve option defines the level of effect.
To use the tool, select one or more target objects (particles, freeform surfaces), activate the tool and enter two points through the view window to define the deformation axis.
The Axial deformer defines the following options:
To create a tornado:
1. Create a particle cloud
2. Select the particle object, activate the tool and enter two points in the view window to define the symmetry axis for the tornado.
3. Use Hyperbolic control curve with Animation option and appropriate rotation angle.
