Inspector
Controls Tab
The Controls tab is used to set the location and time of the daylight simulation. This will
determine the overall look that is generated.
Location
The Latitude and Longitude sliders are used to specify the location used to create the Day Sky
simulation.
Date and Time
The Day, Month, and Time controls are used to select the specific time for the Day Sky
simulation.
Turbidity
Turbidity causes light to be scattered and absorbed instead of transmitted in straight lines
through the simulation. Increasing the turbidity will give the sky simulation a murky feeling, as if
smoke or atmospheric haze were present.
Do Tone Mapping
Since the simulation is calculated in 32-bit floating-point color space, it generates color values
well above 1.0 and well below 0.0. Tone mapping is a process that takes the full dynamic range
of the resulting simulation and compresses the data into the desired exposure range while
attempting to preserve as much detail from the highlights and shadows as possible. Deselect
this checkbox to disable any tone mapping applied to the simulation.
Generally, this option should be deselected only if the resulting image will later be color
corrected as part of a floating-point color pipeline.
Exposure
Use this control to select the exposure used for tone mapping.
