 - All meshes are "smooth" shaded. The outline shader does not handle flat shading. To achieve an angled look, hand-drawn lines can be added in texture.
 - Space can be left between submeshes to allow the outline shader to fill in the gaps. Enabling clear separation between parts of a model that is otherwise difficult to create due to the unshaded look.
