With the default blend mode of
SCNBlend, materials blend according to their alpha (opacity) values—a pixel rendered with a higher alpha value appears more opaque than one with a lower alpha value. Change this property to create special effects. For example, the
SCNBlend mode can make objects appear to glow.
