I have this script in Python which I'm running into a maya file from a command line:

import maya.standalone
maya.standalone.initialize("Python")
import maya.cmds as cmds
from maya import cmds
import maya.mel as mel
import glob


def importFile(i):
    cmds.file(i, i=True, groupReference=True, groupName="myobj")


def materialFile():
    if cmds.objExists('Panel*'):
        cmds.select("Panel*", replace=True)
        myMaterial = "BlueGlass"
        cmds.sets( e=True, forceElement= myMaterial + 'SG' ) 

    if cmds.objExists('Body*'):
        cmds.select("Body*", replace=True)
        myMaterial3 = "Silver"
        cmds.sets( e=True, forceElement= myMaterial3 + 'SG' )

But I get this error when I try to run the batch file:

File "/Users/../Scripts/MayaVectorScript.py", line 23, in materialFile
        cmds.sets( e=True, forceElement= myMaterial + 'SG' ) 
TypeError: No object matches name: BlueGlassSG

In the Hypershade, the shader BlueGlass is connected to a shader group (SG) with the same name BlueglassSG and the script works from the UI inside maya.

Do I need to load a plugin or something in the script to make it run in the batch file?

Released from spamqueue. Anyone with maya experience?

Where is the whole script? 

The maya file should trigger loading any plugins you need. If you save out as maya asci you will see the requirements. 
But there are some parts of the system that only become live if you have the UI available. 

If you start a normal maya session with your code as a script does it run?
