Paint
Shake provides simple paint capabilities using the
QuickPaint node. This chapter describes how to use the
non-destructive tools found within this node to make fast
fixes to your image sequences.
About the QuickPaint Node
The QuickPaint node is a touch-up tool to fix small element problems such as holes in
mattes or scratches/dirt on your plates. It is a procedural paint tool, which allows you to
change strokes long after they’ve been made. This helps to emphasize its key feature—
it is simply another compositing tool that can easily be used in conjunction with any of
Shake’s other nodes. You can apply an effect and easily ignore it, remove it, or reorder it
after you have applied your paint strokes.
The tools within the QuickPaint node respond to the pressure sensitivity found in most
pen-based digitizing tablets.
Connecting Input Images to the QuickPaint Node
The QuickPaint node has two inputs. The first one lets you connect a background
image to paint on, and also acts as the clone source. The second input is used by the
Reveal tool—Reveal paint strokes expose the image that’s connected to the second
input (for example, a clean background plate), allowing you to replace portions of the
first image with portions of the second image.
Setting the QuickPaint Node’s Resolution
You can apply a QuickPaint node to another node, or you can create an unattached
“floating” QuickPaint node that can be composited later with other nodes using one of
the Layer functions, or used as a mask operator. QuickPaint nodes that are attached to
other nodes assume the resolution of the node tree.
Floating QuickPaint nodes inherit the defaultWidth and defaultHeight of the script. To
change the resolution of a floating QuickPaint node, create a Color or Window node,
and attach the QuickPaint node underneath. Setting the resolution in the Color or
Window node parameters will then determine the resolution of the QuickPaint node.
