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:
• 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.
|
Light List |
Pick Item: Lets you define a light in your scene that will be used to compute the fast lens effect. Remove Selected: Lets you remove a selected light from the light list. Once removed, the light will no longer influence the effect created by the shader. |
|
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. |
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. |
This shader can be applied directly to the camera in the lens shader stack. See Adding Lens Shaders to the Camera [Lights and Cameras].
