Sky Texture Node

Noden Sky Texture genererar en procedurell himmel. Den används vanligtvis i kombination med Värld Utgångsnod.

Inmatningar

Vektor

Texturkoordinat att sampla texturen på; standardvärde är Genererade texturkoordinater om sockeln inte är ansluten.

Egenskaper

Typ av himmel

Sky-modell att använda.

Single Scattering

Improved version of the 1993 model by Nishita et al, accounts for single bounces in the atmosphere. This is legacy and may be removed in a future version.

Multipel spridning

Based on this work by Fernando García Liñán, it is the most accurate model as it accounts for multiple bounces of light in the atmosphere.

Preetham

Based on the 1999 paper by Preetham et al. This is legacy and will be removed in a future version.

Hosek/Wilkie

Based on the 2012 paper by Hosek and Wilkie. This is legacy and will be removed in a future version.

Anteckning

Single and Multiple Scattering skies are very bright by default (hence accurate). You can lower the Exposure of the scene in Properties ‣ Color Management ‣ Exposure to fix this.

Sun Direction

Sun direction vector.

Turbidity

Atmospheric turbidity.

• 2: Arctic like

• 3: clear sky

• 6: warm/moist day

• 10: hazy day

Ground Albedo

Amount of light reflected from the planet surface back into the atmosphere.

Sun Disc Cycles Only

Aktivera/inaktivera solskivans belysning.

Solens storlek

Vinkeldiameter på solskivan (i grader).

Solens intensitet

Multiplikator för solskivsbelysning.

Solhöjd

Solens rotation från horisonten (i grader).

Solens rotation

Solens rotation runt zenit (i grader).

Höjd över havet

The distance from sea level to the location of the camera. For example, if the camera is placed on a beach then a value of 0 should be used. However, if the camera is in the cockpit of a flying airplane then a value of 10 km will be more suitable.

Luft

Density of air molecules. A value of 1 corresponds roughly to urban city air, while 0 is no air.

Aerosols

Density of aerosol particles (water droplets). A value of 1 corresponds roughly to urban city aerosols, while 0 is no aerosols.

Ozon

Density of ozone molecules; useful to make the sky appear bluer. A value of 1 corresponds roughly to urban city ozone, while 0 is no ozone.
