Double Poly: Allows softening part of the spline curve while keeping other portions
of the curve sharp. The double polyline is composed of two shapes, an inner and
outer shape. The inner shape is the original shape from the single polyline, whereas
the outer shape is used to determine the spread of the softness. The further the outer
shape gets from the inner shape, the softer that segment of the shape becomes. Both
polylines start with exactly the same shape as the original single polyline, keeping the
mask sharp to start. Any animation already applied to the shape remains. To select
the outer shape, press the Tab key to cycle between the onscreen controls until the
dashed outline is visible, or you can select the outer polyline using the contextual
menu’s Controls > Outer Polygon menu.
Multiframe: Multiframe is a method of adjusting control points across multiple
keyframes. The default setting of none only adjusts the control point of a spline on the
current keyframe. Setting the menu to All adjusts the controls point for all keyframes.
Prev settings adjust the current and previous keyframe while Next adjusts the current
and next keyframe.
Onion Skinning: Enabling onion skinning displays a mix in the viewer of the spline
animation. It is useful when aligning spline animation and motion. Selecting Onion Skin
Settings from the drop down menu allows you to set the number of overlapping frames.
Roto Assist: Enable the Roto Assist button when you begin painting with the Polyline
Stroke tool. The polyline points snap to the closest edge as you click to add points to
the shape. A cyan outline indicates the points that have snapped to an edge. There are
three main Roto Assist options selectable through the drop down menu:
Multiple Points: When enabled, a single click on a high contrast edge adds multiple
points to define the entire edge, instead of having to add each point individually.
This is a one time only click. The second click reverts to single point edge detection.
Distance 8: Opens a dialog where you can set the pixel range within which
searching for an edge takes place.
Reset: Used for resetting the snap attribute of all snapped points. After resetting, the
points become unavailable for tracking.
Change the way the toolbar is displayed by right-clicking on the toolbar and selecting from the
options displayed in the toolbar’s contextual menu. The functions of the buttons in this toolbar
are explained in depth in the Polylines chapter.
Ranges Mask [RNG]
The Ranges node
Ranges Mask Node Introduction
Similar to Bitmap mask, the Ranges mask allows images from the node tree to act as masks for
nodes and effects. Instead of creating a simple luminance-based mask from a given channel,
Ranges allows spline-based selection of low, mid and high ranges, akin to Color Corrector.
