Map a label to a shader

In the shader’s Control Window, click the Map button to the right of the Color parameter. The Texture Procedures window appears.
If you are planning to mask the label, continue with step 2.

If you do not need to mask the label, you can skip to step 4.
In the Texture Procedures window, click the Stencil button.
The Texture Procedures window automatically closes, a Stencil texture swatch appears in the Multi-lister, and the Control Window displays the texture’s parameters.
In the Stencil texture’s Control Window, click the Map button beside the Image field. The Texture Procedures window appears.
In the Texture Procedures window, click the File button. The Texture Procedures window automatically closes, a File texture swatch appears in the Multi-lister, and the Control Window displays the texture’s parameters.
In the Control Window, type the name of the image file you want to use as the label in the Image field, or click the Browse button and select the image file using the File Requestor.
The image file is now mapped onto the shader, and appears on the shader swatch in the Multi-lister. By default, the image file covers the entire shader. However, you can limit the area it covers by masking the label or positioning it on the shader.
