but in general, spec seems to provide practical guidance:

12.4.6 TwoSidedMaterial

"If the separateBackColor field is set to TRUE, the rendering shall render the front and back faces of the geometry with different values. If the value is FALSE, the front colours are used for both the front and back side of the polygon, as per the existing X3D lighting rules."

all the best, Don
