Starburst Flare

 
 
 

DEPRECATED. This shader is unsupported, but it may still get installed with Softimage to provide compatibility with older scenes that use it. It is recommended that you replace unsupported shaders in your scenes with equivalent shaders from the current Softimage shader library.

Category: Lens

Shader Type: Lens

Output: Color (RGB) value

Creates a lens flare using the illumination from a selected light source, and is distinguished by its realistic star-like flare. The flare's brightness and saturation can be defined, as well as which light(s) will flare. In addition, this shader lets you define a halo, a star effect, and ghost circles.

Can be applied in several instances onto a camera. A flare appears in the alpha channel for compositing.

Tips:

Flare Lights

Light List

Lets you define a light in your scene that will be used to compute the fast lens effect.

Visibility

Uses a virtual radius to estimate how much of the light source is seen. The flare decreases in relation to how much the light source is obscured. When off, the shader's flare effects are visible, regardless of whether the light source is direct or obscured.

Render Flares Only

Renders only the flare on a black background. Saves rendering time and makes image composition easier later.

Flare Settings

Halo

Halo

Creates a halo around the flare.

Intensity

Defines the brightness of the halo. Default value is 1.

Size

Defines the size of the halo. A value of 1 creates a halo that will cover the entire image.

Star

Star

Creates a star-flare effect on the camera's lens.

The star's rays can be defined with the following parameters:

Number of Rays

Controls the number of rays per star.

Length

Defines the length of the star's ray.

Length Jitter

Defines the random sampling that will occur on a star's length when rendered.

Thickness

Defines the thickness of the star's ray.

Thickness Jitter

Defines the random sampling that will occur on a star's thickness when rendered.

Angle Start

Defines the angular distribution of stars.

Angle Inclination

Defines the inclination of the stars.

Rotate Source

Makes the star effect rotate automatically as the light source is moved.

Circles

Circles

Creates a defined number of ghosts on the lens.

Intensity

Controls the number of ghost circles that will be created on the lens.

Desaturation

Controls the coloring of the ghost circles.

Line Streaks

Creates random line streaks around the light's position.

Render Tree Usage

This shader can be applied directly to the camera in the lens shader stack.
