- Mode:
- Simple: In simple mode, the same image is used for mapped spherically on all four channels, and a . A single set of controls for rotation and scale affects all the channels channels equally. The channels can be enabled and disabled individually, however, and their relative intensities can be independently adjusted.
- Detailed: In detailed mode, each channel is completely independent from the others, and can be mapped with its own image, have unique rotation and scale parameters, etc.
Open: Select HDRI from disk.
Delete: Remove link to HDRI.
View: View HDRI preview.- Background: When checked, the background channel will be enabled. This channel adds an IBL map that provides a background image for the scene. This channel does not provide any scene illumination or reflections.
Reflection: Adds an IBL map for reflections on objects within the scene. This map will be visible in any objects that have a reflective material applied to them.
Refraction: Adds an IBL map for refractions within objects in the scene. This map will be visible through objects that are transparent and refractive, ie. which have ND higher than 1).
Illumination: Adds an IBL map for illuminating the scene. This map will be used to illuminate the scene.
- Intensity: Adjust the intensity of the map to increase or decrease its contribution to scene illumination, reflections, or refractions.
- Rotation Azimuth, Rotation Altitude: Rotates the spherical environment. (In degrees.)
- Scale Azimuth, Scale Altitude: Scales the current map. (Multiplier)
- Mapping:
- Spherical: The background will be mapped to the entire spherical environment dome.
- Screen: The image will mapped to the width and height of the output image. This option is only available for the background channel in Detailed mode; in Simple mode, the background mapping with be spherical. The other three channels are mapped spherically in either mode.
