-**Camera Altitude:** - The altitude of the camera in the world in meters
-**Azimuth Angle:** - The solar azimuth angle of the sun measured via a spherical coordinate system. North is 0/360°, East is 90°, South is 180° and west is 270°.
-**Zenith Angle:** - The altitude of the sun based on the angle between the horizon and the centre of the Sun's disc.
-**Sky Type:** - Here you can choose if the atmosphere is cloudy or partially cloudy.
-  * **Default** - Default has a cloudy atmosphere
-  * **Partially Cloudy** - Partially Cloudy has a partially cloudy atmosphere.
