Back Face
Back Face provides options for modifying the base color, emission, and alpha for the backfaces of a mesh.
On 3D models, meshes typically only show it's faces on one side, that being the front-facing side. The back-facing side of the mesh is usually see-through, an effect that you can get when you are looking from inside a model. Shaders can control this behavior, forcing the back-facing side of the mesh to also render if the user desires for whatever reason.
