Lit Fog |
Creates volumetric lighting effects, such as a shaft or cone of scattered light in fog, haze, or smoke.

Lit fog cannot be applied to directional, area, or line lights. |

Specifies the fog density; enter a larger value to increase the density of the effect |
|
Fog Consistency |
Creates either a smooth or uneven fog effect |
|
Receive Shadows |
Allows the effect to be blocked by solid objects, creating shadows; for example, when blocking a shaft of light by a table, so that light does not display under the table. Use Shadows must also be selected in the rendering options. |
The new background resource is listed in the Resource Manager. It is available for the Set Renderworks Background command, in the Edit Design Layers dialog box (see Applying Renderworks backgrounds for information), and on the Object Info palette for viewports.
To quickly edit a Renderworks background, press Ctrl (Windows) or Option (Mac) and double-click on the resource in the Resource Manager.
Backgrounds and lit fog effects can be used together.
Purge textures and backgrounds that are not used in the drawing file to reduce file size. See Purging items from a file.
