Corona Front Back Shader is a simple shader that allows you to assign different colors/texture maps to a surface based on the orientation of the normal (front face / back face). This is useful, for example, for backface culling when used in the Opacity channel, for assigning print to the front of a label on a bottle, or for plain paper on the back of the same label (seen through the glass of the bottle).

Swap front and back - Allows swapping the texture maps for the front/back faces.

These parameters apply only to the polygon's front face.

Level - Determines the front face color strength.

Color - Sets the color for the polygon's front face.

Texture - Overrides the color slot with the use of a shader.

Mix mode - Controls the blending mode between the color and the texture slot.

Mix strength - Determines the mixing strength of the color and the texture slots.

These parameters apply only to the polygon's back face.

Level - Determines the back face color strength.

Color - Sets the color for the polygon's back face.

Texture - Overrides the color slot with the use of a shader.

Mix mode - Controls the blending mode between the color and the texture slot.

Mix strength - Determines the mixing strength of the color and the texture slots.

Corona Front Back Shader is used to apply a single material to the play cards with different texture maps for the front/back faces.
