Plane Animation

Use this modifier to animate spline primitives using a NURBS plane. Each primitive is bound to the surface of the NURBS plane by using a calculation that matches primitive locations to the closest CVs on the surface of the plane. By default, XGen uses the number of CVs on the NURB surface for binding the primitives. You can further subdivide the NURBS surface by setting the Plane Subdivs U and Plane Subdivs V values. Increasing the subdivisions can result in a better binding with the primitives and a smoother animation.

Your input curve should have enough CVs to reflect the shape of the nurbs surface, or at least as many CVs as the higher count direction of the plane. To compute the binding information, you must create a statice reference frame for the NURBS plane. To do this, go to the frame you want to use as the reference frame, then click Freeze Plane.

Mask

Controls the strength of the modifier effect. You can use Mask to load a map that specifies how areas of the mesh surface are affected by the modifier.

Magnitude

Sets the amount of the plane's animation you want to apply to the primitives.

Plane Names

Specifies the name of the Alembic (.abc) cache file containing the NURBS plane you want to use as the animation plane.

Plane Subdivs U

Sets the number of subdivision in the NURBS surface along the U direction.

Plane Subdivs V

Sets the number of subdivision in the NURBS surface along the V direction.

Freeze Plane

Creates a static reference frame of the NURBS plane for the binding information.
