You can add a texture or color swatch to a style catalog as a material style. Materials are tiled over the surface of the object to which they are applied.
For colors, enter the hexadecimal value representing the color, or click Browse and navigate to the file representing the color.
The supported color format is <xRRGGBB(AA)> or <#RRGGBB(AA)> with R, G, B, and A being the hexadecimal representations of the red, green, blue, and alpha channels of the color. The definition of the alpha channel is optional. It defaults to FF, which is fully opaque.
For more information regarding these settings, refer to Edit Styles.
The style thumbnail appears in the catalog. Click in the name area to rename it.
