With WPF 3D, is it possible to have a texture with an alpha channel? I am wanting to make a 3d scene where everything is flat surfaces (like everything is paper cutouts).

Was talking to a colleague about XAML and how it is both a presentation and object description language and therefore quite unique and novel among IT technology.
