You
create illuminated fog by adding it to an existing light.
NoteTo create fog that
fills the entire scene, not just within the illumination of a specific
light, use the Env(iroment) Fog Volumetric material.
To add illuminated fog to a light
- Select the light for which you want to
illuminate fog.
- In the Light Effects section
of the light’s Attribute Editor, click the
map button beside the Light Fog attribute.
Maya automatically creates
a light fog node, connects it to the light node, and displays its Attribute
Editor.
