| Lights | Smoke | Render Tree Usage
Shader Type: Volume
Output: Color (RGB) value
When used with the Fast Lens Effects light shader, gives a volumetric effect to lights. Both the Fast_volume_effects and the Fast_light_effects light shader must be used for each light that is to receive volumetric effects. If no Fast_light_effects shader is used, the light will have no volumetric effects.
|
Name |
The shader’s name. Enter any name you like, or leave the default. |
Lights
|
Light List |
Pick Item: Defines a light in your scene that will be used to compute the fast lens effect. Remove Selected: Removes a selected light from the light list. Once removed, the light will no longer influence the effect created by the shader. |
Sampling
|
Feature Size |
Controls the steps of a volume map. Use this to “smooth” the volumic effect. |
|
Max Ray Length |
Sets an upper limit on the distance that light rays travel in a volumic environment. |
|
Smoke |
When on, it overlays a “smoky” effect over the volumetric effects. |
|
Depth Fading |
When on, it Switches on the calculation of depth fading in addition to the volumetric effects. |
|
3D Smoke |
Specifies the Z-depth of the smoke. |
|
Scale |
Specifies the size of the smoke. |
|
Intensity |
Specifies the thickness, or density, of the smoke. |
|
Animation Speed |
Specifies the distance smoke will travel over time. |
This shader is applied to a scene using the shader stack. Volume shaders cannot be expanded or built upon in the render tree.
