Because DiffuseMaterial, SpecularMaterial, and EmissiveMaterial provide distinctly different effects, it's useful to combine them. For example, you might choose to apply a complex texture to a mesh using DiffuseMaterial, while adding a highlighting effect with a SpecularMaterial on the same mesh. MaterialGroup allows you to treat these Materials as a single texture for convenience.

The following excerpt shows a MaterialGroup.

<MaterialGroup x:Key="LeavesMaterial1">
  <DiffuseMaterial>
    <DiffuseMaterial.Brush>
      <ImageBrush Stretch="UniformToFill" ImageSource="sample_images\leaves_closeup.png" TileMode="None" ViewportUnits="Absolute" Viewport="0 0 1 1" AlignmentX="Left" AlignmentY="Top" Opacity="1.000000" />
    </DiffuseMaterial.Brush>
  </DiffuseMaterial>
  <SpecularMaterial SpecularPower="85.3333">
    <SpecularMaterial.Brush>
      <SolidColorBrush Color="#FFFFFF" Opacity="1.000000"/>
    </SpecularMaterial.Brush>
  </SpecularMaterial>
</MaterialGroup>
