Image Based Parameters

The Image Based Environment Type allows you to light the scene using HDR images. There are four Image Based Channels provided:

 Background: this image will be seen where the background is directly visible to the camera

 Illumination: this image will be used to illuminate the scene

 Reflection: this image will be seen in reflections in the scene

 Refraction: this image will be seen where light is refracted in the scene

Each channel shares a few similar parameters and a similar operation:

 Path: this is the path to an .mxi, .hdr, or .exr file which will be used in the channel

 Enabled: this checkbox is only shown when it is possible to enable the channel

 Scale U/V: scales the input image in width and height such that n-number of tiles will be fit into the mapped area

 Offset U/V: shifts the image up or down by n-percent

 Intensity: alters the basic output power given to this channel’s image

 Screen Mapped: this parameter is only present in the Background channel. It causes the Background channel to be mapped flat

against the image plane, rather than spherically.

Parameters which have no context, given the state of other parameters, are not shown. For example, until a channel’s path has been set

to point to a valid file, nothing is shown for that channel except for the path chooser. When a path has been specified, but the channel

is not enabled, all of the parameters, except for the path and the ‘Enabled’ checkbox, will not be shown.

As a shortcut, holding down CTRL while adjusting parameters in one channel will cause the change to be effected in all four channels.
