+The Lambertian material represents a one-sided ideal diffuse material
+with the specified amount of reflectance. Optionally, a texture map may
+be applied. If no extra information is provided, the material will revert to 
+the default of uniform 50% reflectance.
+
+Seen from the back side, this material will appear completely black.
