Style
The Style tab is used to assign color to the shape and control its transparency.
Color
The Color controls determine the color of the fill and border from the sStar node. To choose a shape
color, you can click the color disclosure arrow and use the color swatch, or drag the eye dropper into
the viewer to select a color from an image. The RGBA sliders or number fields can be used to enter
the value of each color channel or the strength of the alpha channel.
Allow Combining
When this checkbox is enabled, the alpha channel value is maintained even when passing through
other nodes downstream that may cause the shape to overlap with copies of itself. When disabled, the
alpha channel value may increase when the shape overlaps itself. For instance, if a star alpha channel
is set to .5, enabling the Allow Combining checkbox maintains that value even if the shape passes
through a duplicate or grid node that causes the shape and alpha channel to overlap. Disabling the
checkbox causes the alpha channel values to be compounded at each overlapping area.

Common Controls
Settings tab
The Settings tab in the Inspector is common to all Shape nodes. These common controls are
described in detail at the end of this chapter in “The Common Controls” section.
sTransform
The sTransform node
The sTransform node is used to add an additional set of transform controls to the existing controls that
are contained in Shape nodes. These additional transforms can be used to create hierarchical
animations. For instance, you can use a sStar’s built-in Angle control to spin the star around. The star
can then be output to an sTransform node. The rotation control in the sTransform can be used to orbit
the star around the frame.
Like almost all Shape nodes, you can only view the sStar node’s results through a sRender node.
