The background mode. See [enum BGMode] for possible values.

Blend factor between the fog's color and the color of the background [Sky]. Must have [member background_mode] set to [constant BG_SKY].
This is useful to simulate [url=https://en.wikipedia.org/wiki/Aerial_perspective]aerial perspective[/url] in large scenes with low density fog. However, it is not very useful for high-density fog, as the sky will shine through. When set to [code]1.0[/code], the fog color comes completely from the [Sky]. If set to [code]0.0[/code], aerial perspective is disabled.
