User Manual

–
Write On: When Write On is selected, an animation spline is added to the paint
stroke that precisely duplicates the timing of the paint stroke’s creation. The stroke
is written on the image exactly as it was drawn. To adjust the timing of the Write On
effect, switch to the Spline Editor and use the Time Stretcher node to adjust the
overall length of the animation spline. To smooth or manually adjust the motion, try
reducing the points in the animation spline.
–
Write Off: Write Off performs the reverse of Write On, drawing the stroke starting
from the end and working backward to the start of the stroke.
–
Write On Then Off: This menu option applies a Write On and then a Write Off
animation mode to the stroke.
–
Trail: Selecting the Trail option from the menu causes both the start and end points
of the stroke to be animated simultaneously, offset from each other by the amount
specified in the Duration control. This has the effect of creating a painted segment
that follows the stroke path. As with the Write On and Write Off effects, this starts on
the current frame when the animation mode is selected. The timing of the animation
can be adjusted manually using the Spline or Keyframes Editors.
 Duration: Duration sets the duration of each stroke in frames. This control is present
only for Multistroke and Clone Multistroke, or when the stroke animation mode is set
to Limited Duration. It is most commonly employed for frame-by-frame rotoscoping
through a scene.
Each Vector stroke applied to a scene has a duration in the Keyframes Editor that can
be trimmed independently from one stroke to the next. The duration can be set to 0.5,
which allows each stroke to last for a single field only when the node tree is processing
in Fields mode.
 Write On and Write Off: This range slider appears when the Stroke Animation is set to
one of the Write On and Write Off methods. The range represents the beginning and
end points of the stroke. Increase the Start value from 0.0 to 1.0 to erase the stroke, or
increase the End value from 0.0 to 1.0 to draw the stroke on the screen. This control
can be animated to good effect. It works most effectively when automatically animated
through the use of the Write On and Write Off modes of the Stroke Animation menu.
 Make Editable: This button appears only for Vector strokes. Clicking on Make Editable
turns the current stroke into a polyline spline so that the shape can be adjusted or
animated.
Paint Node Modifiers
Every paint stroke created in the viewer creates an associated modifier stroke. These modifier
strokes are represented as a list of paint stroke operations in the Modifiers tab of the Inspector.
Each stroke you create can be modified or deleted, or applied in a different order using the
modifier stack.
NOTE: The MultiStroke tools are built for speed and can contain many strokes
internally without creating a huge list stack in the modifiers
Each Paint modifier stroke contains Brush controls, Apply controls, and Stroke controls identical
to those found in the main Controls tab of the Inspector.
