Public Attributes
glm::vec3	radiance = {0.004f, 0.006f, 0.014f}
	Skyglow the scene is lit by, so night is dark, not black.
float	moonTilt = 15.0f
	Degrees off directly opposite the sun.
float	moonAngularRadius = 0.03f
	Radians.
float	moonIntensity = 1.2f
	Disc radiance; its halo follows.
float	starIntensity = 3.0f
	0 disables; the default clears the bloom threshold.
float	starDensity = 140.0f
	Higher packs more, smaller stars.

Static Public Attributes
static constexpr float	TWILIGHT_DEGREES = 8.0f
	Degrees either side of the horizon across which day hands over to night.

Detailed Description

What the sky is once the sun is down.

Single scattering at night is nearly black, so night's light is authored. It fades in across TWILIGHT_DEGREES around the horizon.

float Vkm::Engine::NightSkySettings::TWILIGHT_DEGREES = 8.0f

staticconstexpr

Degrees either side of the horizon across which day hands over to night.

Read by SkySystem and shaders/sky.glsl (as a sine, via the prelude).
