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
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:
-
When using several instances of this shader, turn off the Render Flares Only parameter on all instances except for the last
one. This will prevent mental ray from rendering the entire scene.
-
To apply different flare effects on different lights, apply this shader multiple times to the same camera and select different
lights each time.
Flare Lights
|
Lets you define a light in your scene that will be used to compute the fast lens effect.
|
|
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.
|
|
Renders only the flare on a black background. Saves rendering time and makes image composition easier later.
|
Flare Settings
Halo
|
Creates a halo around the flare.
|
|
Defines the brightness of the halo. Default value is 1.
|
|
Defines the size of the halo. A value of 1 creates a halo that will cover the entire image.
|
Star
|
Creates a star-flare effect on the camera's lens. The star's rays can be defined with the following parameters:
|
|
Controls the number of rays per star.
|
|
Defines the length of the star's ray.
|
|
Defines the random sampling that will occur on a star's length when rendered.
|
|
Defines the thickness of the star's ray.
|
|
Defines the random sampling that will occur on a star's thickness when rendered.
|
|
Defines the angular distribution of stars.
|
|
Defines the inclination of the stars.
|
|
Makes the star effect rotate automatically as the light source is moved.
|
Circles
|
Creates a defined number of ghosts on the lens.
|
|
Controls the number of ghost circles that will be created on the lens.
|
|
Controls the coloring of the ghost circles.
|
|
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.
