## Adding a Texture Map

An image file can be imported into a surface visualization to serve as a texture map: an image projected onto the surface skin in place of the default red skin.

To add a texture map to a surface:

1. Select the surface.

2. Select Edit Parameters to open the Parameter Editor.

3. Click Import File to import the image file to be used as a texture map into the Data Manager.

4. Find the image file in the list of files in the Data Manager tree and select either a specific image channel to import, or select Image Planes to import all channels of the image.

5. Click the Assign Data button under TEXTURE. The name of the data to import appears in the TEXTURE field.
