Double-sided shaded surfaces
 
 
 

Double-sided shading lets you shade a surface with one material on one side and a different material on the other side. This is the only way you can apply more than one material to a NURBS surface. You use both the Condition and Sampler info utility to create this effect. For more information on these utility nodes, see Utilities.

To create double-sided shaded surfaces, see Create double-sided shaded surfaces.
