8.Enviro
In this section, you can setup everything else that is environment related, such as Sky, Haze and Fog, Sun and Moon, Ocean, Clouds, and Wind.
Sky
Here you can choose whether to render a simple colored background or an ultra-realistic skybackground that supports atmosphere scattering effects, and more.
Mode lets you choose between None (simple background color) and Realistic (true atmosphere scattering and lighting).
If None is chosen, you can use the Time of Day sliders, to adjust the time of day resulting in a different light direction that is, the direction from which the terrain surface receives light rays. Color lets you choose the background color.
If Realistic is chosen, you additionally will see the Play checkbox, that automatically will increase the general time to simulate a day-night cycle. Once checked, the Time of Day parameter is replaced by the Speed parameter. With Disable Skybox Ocean you can toggle the ocean rendering along the horizon on / off.
Haze and Fog
Here you can adjust haze, atmosphere scattering and fog parameters.
Thickness indicates the atmosphere thickness. Wavelengths lets you adjust the wavelength for red, green, and blue. Changing these values will result in a different world- and atmosphere color.
World Inscatter toggles light scattering on the terrain on/off. Intensity and Extinction, lets you adjust the intensity of the world inscatter effect.
With Scale and Near Push, you can adjust the starting distance and scale of the world inscatter effect.
Fog> toggles fog on/off. If Lock to Sky-Color is enabled, the fog will color itself depending on the world inscatter color, else, you can choose a fog color with Colo. Density lets you adjust the fog density. Start Distance lets you adjust the distance at which fog will start. Height Fog toggles height-based fog on/off.
Height lets you adjust the height at which the height-based fog will get visible. With Height Density you can adjust the density for the height-based fog.
Exclude Far Pixels toggles whether fog should be considered by the skybox. Radial Distance toggles whether fog distance is based on radial distance from point of the viewer.
Sun and Moon
World Creator has a realistic day / night rendering system. Within this section you can adjust the sun and moon properties.
Sun Size lets you adjust the size of the sun disc. Sun Intensity lets you adjust the general sun light intensity.
Moon Intensity lets you adjust the general moon light intensity.
Exposure, Mie Scattering, and Anisotropy Factor lets you adjust the overall rendering of the sun disc in combination with the light rays surrounding the sun disc, as well as the overall lighting intensity.
Sun Shafts toggles sun shafts on/off. Scale lets you adjust the sun shafts size. Radius lets you adjust the sun shafts radius. Threshold lets you adjust the threshold at which sun shafts become visible.
Use Light Color lets you choose whether to use the light color based on the sun color in combination with atmosphere scattering effects or to choose a custom color with Color.
Ocean
In the previous chapters, you might have recognized a Relative to Ocean property for the filters, the textures, the objects, and details. With that property set, the Height Range property is interpreted as a relative value which depends and adapts itself to the set Ocean Height.
Show Ocean Plane lets you toggle the ocean rendering on / off.
Changing the Ocean Height while filters, textures, objects, and details are in dependence of it, allows you to quickly adapt the whole generation process.
The Diffuse Color specifies the general color of the water. With Specular Color, you can adjust the specularity color behavior. With Reflection Color, you specify the color for reflections.
The Sub Surface Scattering indicates, how much light should be scattered back from the underwater.
Water Drops Intensity ndicates the strength at which water drops are rendered, after the camera gets out of water.
Clouds
World Creator uses a clouds texture to render the sky. That texture can be chosen within this section as well as adjusted with the available parameters.
Texture lets you choose a texture from the media library. Rotation Speed indicates the cloud density. Density indicates the cloud density.
The other parameters are used to tweak the cloud rendering system. You should quickly try them out on your own to figure out how they behave.
Wind
World Creator supports realistic wind calculations that affect objects and details.
Direction lets you adjust the wind direction.
Intensity determines the overall strength of the wind, but this can be given little random variation using Turbulence.
The wind blows over objects and details in pulses to create a more natural effect. The strength of the pulses and the time interval between them can be controlled using the Magnitude and Frequency properties.
