Star
The Star generator creates a glowing star shape that contains an alpha channel. The
scale, width, angle, epsilon (which fine-tunes the size of the star spikes), and opacity of
the spikes can be modified and keyframed, as well as the position, color, and radius of
the star.
Parameters in the Inspector
Center: Sets the position of the center of the star.
Color: Picks the halo around the star. Use the disclosure triangle to display Red, Green,
Blue, and Alpha sliders for more precise color selection.
Radius: Sets the radius of the circle at the center of the star. Values range from 0 to 300.
Spike Scale: Sets the size of the star spikes. Values range from 0 to 100.
Spike Angle: Sets the angles of the star spikes.
Spike Opacity: Sets the opacity of the star spikes. Values range from –8 to 0.
Spike Width: Sets the width of the star spikes. Values range from 0 to 50.
Epsilon: Fine-tunes the strength of the star spikes.
