Maya command to create a lambert shader & shading group node named for the object

applyMayaMaterial.py

import maya.cmds as mc

def applyMaterial(node):
    if mc.objExists(node):
        shd = mc.shadingNode('lambert', name="%s_lambert" % node, asShader=True)
        shdSG = mc.sets(name='%sSG' % shd, empty=True, renderable=True, noSurfaceShader=True)
        mc.connectAttr('%s.outColor' % shd, '%s.surfaceShader' % shdSG)
        mc.sets(node, e=True, forceElement=shdSG)

applyMaterial("pSphere1")

Many thanks

Is there any way to duplicate the shading node with all connectiones in maya cmds?

Is there any way to duplicate the shading node with all connectiones in maya cmds?

Matching these menu entries:

The logic is roughly:

Duplicate Shading Network

from maya import cmds
cmds.duplicate(upstreamNodes=True)

Duplicate without network

from maya import cmds
cmds.duplicate()

Duplicate with connections to network

from maya import cmds
cmds.duplicate(inputConnections=True)

Thanks a lot. I need to duplicate the shading network. And I use the code cmds.duplicate([mtl, mtl_sg], upstreamNodes=True). It really works. Thanks for your reply.
