The following parameters can be used to define the characteristics of the sun light source.

Manually enter the Date/Time and Location (in geographic coordinates) that will affect your rendering scene.

See also Note on Sun Settings in ARCHICAD. Use this to fine-tune the weather preset you have chosen to match the conditions at the project location.

Use ARCHICAD Sun Position: Checking this box will reset the Time & Location according to the sun location.

Sky Refraction: Turn on/off the Physical Sky’s refraction effect.

Sky Reflection: If only Sky Reflection is on, then you can, for example, see the environment reflected on a glass building, without rendering the environment itself.

Sky Luminance: You can turn on Sky Luminance with the other effects off: this will give you the light effect of the Physical Sky without anything else.

Sky Visibility: If you turn this off, the Physical Sky parameters still affect the rendering, but you cannot see the sky itself.

However, you can turn any of them off, or leave just one of them on, to achieve certain effects and/or optimize rendering time.

The following effects are on by default, and their respective parameters are defined in the weather presets. It is “smart” and the parameters are interconnected.Ĭhoose Physical Sky from the Sky Setup parameter.

A Physical Sky provides both a background image and lighting effects. The Physical Sky is an entire constellation that includes multiple objects having properties (sun, weather, clouds, fog, rainbow, atmosphere).
