Skybox as a background

What is a skybox?

A skybox is an image that describes the look of your surrounding. Its basically a sphere around you, which is textured with an image. As you now, textures are rectangles – if you want to map them onto a sphere, you have to unwrap the skybox like it’s done with a world map. This format is called Longitude/Latitude, one term for one axis.

There is another way to save the skybox into a file, unlike Longitude/Latitude. It is called the cross format and looks like an unfolded cube. Both image formats are supported by Enscape and can be loaded.

Usually, in a normal image like a JPG, the sun has the same white-value than a bright peace of paper. For lighting purpose, this is not enough. A high dynamic range panorama therefore contains more information than your monitor can display to incorporate the extreme brightness differences. Using Enscape’s virtual camera exposure, you can explore the different lighting scales in your image.

How can I load a skybox?

To load a skybox, open the Enscape Settings and go to the General Settings tab. Here, click on Load Skybox from File to select a file. Enscape supports Skybox image files (*.hdr, *.bmp, *.jpg, *jpeg, *png, *tif, *.tiff, *.tga) either in cross or panoramic (Longitude/Latitude) format.
