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.

Disable Culling to use this feature!

To use this section, Cull must be set to Off in order for backfaces to be visible. Find this option under Rendering.
