Using an Acceleration Plane Manipulator

Like Acceleration Point and Acceleration Line, the Acceleration Plane manipulator continually pulls particles toward itself. With Acceleration Plane, however, particles are manipulated on only one axis set by rotating the plane using the Rotation fields.

Use the Axis controls to position the Acceleration Plane manipulator in the scene. The Scale and fields are not used.

Magnitude is the gravitational pull in pixels per frame. A higher magnitude produces a higher gravity, which results in a greater influence. Power is the falloff from the manipulator, or the radius, of the pull.

The following figure provides an example of creating a simple particle stream influenced by the Acceleration Plane manipulator. The settings in the Particle Manipulator menu and the resulting effect are shown.

NoteBecause Acceleration Plane influences particles on only one axis, the effect may not be noticeable until you change views or orbit the camera.
