Depends on a space-mapping shader (such as Cubic Mapping 1 or Cubic Mapping 6 shaders) to produce color at a given UV coordinate. This shader looks up a texture image in the half-open interval.
Use this shader whenever you wish to use an image clip in a render tree. Only one image clip can be defined per image shader. To blend several images, you can connect them to a Mix 8 Colors shader.
The image shader can be connected to any color input, whether it be a Surface shader, an Image Processing shader, a Mixer shader, or an Environment shader to create an environment map. On a surface shader, you can use a different image shader to define a separate texture for the Diffuse, Specular, Reflection (to create a reflection map), Transparency (to create a transparency map), etc.
Connect a Texture Space Controller shader to drive the Coordinate value of this shader.
