Setting Nighttime Atmospheric Effects

To add dynamic nighttime atmospheric effects, you set various horizon, moon, and star field parameters.

To set nighttime atmospheric parameters

  1. In Lumberyard Editor, choose Tools, Other, Time Of Day.

  2. In the Time of Day Tasks pane, under Tasks, choose Toggle Advanced Properties to view all parameters.

  3. In the Parameters pane, under Night Sky and Night Sky Multiplier, adjust the following parameters as needed:

    Horizon color (and multiplier)

    Specifies the horizon color of the night sky gradient. The RGB value is scaled by the multiplier. You can make a light pollution effect more pronounced by setting this value to a dark blue color (20, 36, 51).

    Zenith color (and multiplier)

    Specifies the zenith color of the night sky gradient. The RGB value is scaled by the multiplier. You can make the night sky gradually appear darker further from the horizon by setting this value to black.

    Zenith shift

    Sets the transition for the two colors in a night sky gradient. Smaller values shift the transition towards the bottom. Larger values shift the transition towards the top. You can create a smooth transition by setting this value to 0.8.

    Star intensity

    Sets the overall brightness of the stars. Star flickering is by design and cannot be controlled. You can make the stars bright for night time by setting this value to 0.01 between 00:00 – 06:00 and 18:00 – 23:59.

    Moon color (and multiplier)

    Specifies the moon's emissive color. The RGB value is scaled by the multiplier. You can make the moon a less saturated blue by setting this value to 51, 58, 65. You can create a light blue transition color by creating two keys at 07:00 and 17:00 and setting the value to 200, 228, 255. Setting this value to 0 removes the moon texture.

    Moon inner corona color (and multiplier)

    Specifies the color of the moon's inner corona (glow around the moon). The RGB value is scaled by the multiplier.

    Moon inner corona scale

    Specifies the size and blurriness of the moon's inner corona. Smaller values create a bigger, blurry corona. Larger values create a smaller, focused corona.

    Moon outer corona color (and multiplier)

    Specifies the color of the moon's outer corona. The RGB value is scaled by the multiplier.

    Moon outer corona scale

    Specifies the size and blurriness of the moon's outer corona. Smaller values create a bigger, blurry corona. Larger values create a smaller, focused corona.
