blendMode
The mode that determines how pixel colors rendered using this material blend with other pixel colors in the rendering target.
Declaration
var blendMode: SCNBlendMode { get set }Discussion
With the default blend mode of SCNBlendMode.alpha, 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 SCNBlendMode.add mode can make objects appear to glow.
