@aske not much has changed. @menno has the shortest example, here is another (in Python, to show it works there too)

def SampleAddRenderMaterials():
    
    # Properties of a Rhino material define what is required to draw an
    # object using OpenGL. Most rendering plug-ins require a much richer
    # defintion than this. And, not all rendering  plug-ins support the
    # same material properties. This is where Render materials come in. 
    
    # A Render material is an abstract material - one that is defined 
    # by the the owning render plug-in. But a basic Render material does
    # share some properties with a Rhino material.
