the lowest density you want to have globally. FogVolumes can be used to add to
or subtract from this density in specific areas. A value of ``0.0`` disables
global volumetric fog while allowing FogVolumes to display volumetric fog in
specific areas. Fog rendering is exponential as in real life. This means fog
will never *fully* obscure objects regardless of distance.
- **Albedo:** The Color of the volumetric fog when interacting with lights. This
multiplies lights' color within the volumetric fog. Mist and fog have an
albedo close to white (``Color(1, 1, 1, 1)``) while smoke has a darker albedo.
This does not affect fog color within FogVolumes.

- **Emission:** The emitted light from the volumetric fog. Even with emission,
volumetric fog will not cast light onto other surfaces. Emission is useful to
establish an ambient color. As the volumetric fog effect uses
single-scattering only, fog tends to need a little bit of emission to soften
the harsh shadows. This does not affect fog color within FogVolumes.

- **GI Inject:** Scales the strength of Global Illumination used in the
volumetric fog's albedo color. A value of ``0.0`` means that Global
Illumination will not impact the volumetric fog. This has a small performance
cost when set above ``0.0``. FogVolumes do not display injected GI regardless
of their albedo color.

- **Anisotropy:** The direction of scattered light as it goes through the
volumetric fog. A value close to ``1.0`` means almost all light is scattered
forward. A value close to ``0.0`` means light is scattered equally in all
