Cubic Mapping 1

Category: Environment

Shader Family: Environment

Output: Color

Is similar to the spherical environment shader. It can accept only one texture mapped on an infinite cube. This tool can be used as a texture, environment, or lens shader.

Because it uses only a single image, this shader can create realistic environment maps that are very memory efficient since it only loads a single image. The only trick is to layout several image portions into one cohesive image to be used by the shader. In order to help tile your images properly, refer to the image below.

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 being presently 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 on the image to access the Image Clip Property Editor. If the image is a sequence, use the playback controls to play the sequence image.
Cube Position (XYZ)	Defines the cube's center position in X, Y, and Z coordinates.
Cube Size (XYZ)	Defines the cube's size in each of the 3 axes. The distances are measured form the cube's center, which is defined in the Cube Position parameter.

Render Tree Usage

This shader can only be connected to the material node's Environment parameter to create an environment map. To create reflection maps, try using an Image shader and connecting it to the Reflection input of the surface shader.
