Two Sided VEX node

Generates a two sided surface.

See also: Front Face, Is Front Face, Lighting Model, Two Tone

This operator generates a two sided surface. The front facing surface and the back facing surface are shaded with different input colors.

No lighting calculation is done in this operator, so either pipe the resulting color into the Diffuse (and Ambient) inputs of the Lighting Model operator, or ensure that the incoming colors are pre-lit.

If the Direction from Eye to Surface (I) or the Surface Normal (N) are not connected, the global variables by the same names will be used instead. Typically, you will not touch ā€œNā€ unless you had applied additional displacement to the surface using an operator such as Bump Noise. If you need to access the global variables directly, they are available from the Global Variables operator.
