Shader Type: Environment (Legacy)
Output: Color (RGB) value
Takes a single image file and maps it to the environment using a spherical mapping. It wraps the image around the Y axis of an imaginary sphere. This is done using longitude and latitude transformations. Just as the longitude lines on a globe move closer at the poles, the image is pinched at the top and bottom of the sphere. The seam where the left and right parts of the image meet is in the negative Z direction.

Causes the texture to make some additional calculations for the ground to allow it to be at a finite distance. In fact, the ground is placed at the Y position 0. This allows objects to change appearance as they move along the ground. Otherwise, the texture is infinitely far away in all directions so that translations have no effect. Moving very close to the ground in this mode can produce artifacts, and the behavior is undefined when below it. |
