Legacy Sphere

DEPRECATED. This shader is unsupported, but it may still get installed with Softimage to provide compatibility with older scenes that use it. It is recommended that you replace unsupported shaders in your scenes with equivalent shaders from the current Softimage shader library.

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.

NoteNo render tree connections are possible with this shader.

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.
