Image Lookup

Category: Data > Map Lookup

Shader Family: Texture

Output: Color

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.

Name	The shader's name. Enter any name you like, or leave the default.
Image	Defines an image clip to use. Click Edit to open a property page for the image clip currently being used. To retrieve a new clip, click New and indicate whether you wish to create a new clip or create one from a source.
Image View Window	Displays the selected image. You can right-click the image to access the Image Clip Property Editor. If the image is a sequence, use the playback controls to play the sequence image.
Coordinate	Define the U, V, and Z texture coordinates.

Render Tree Usage

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.
