how to get faces from a selected shadingEngine

[Chi Ngai Lai]

May I know how to get faces, which might be from different models, from a selected shadingEngine? Could someone help? Thank you very much in advance!

[Andres Weber]

import pymel.core as pm def getFaces(shadingGroup):         pm.hyperShade(objects=shadingGroup)         faces=[]         for obj in pm.ls(sl=True):                 faces.extend( pm.polyListComponentConversion(obj, tf=True) )         return faces         a=getFaces('lambert2SG')

Not crazy about it (I hate things that are selection based) but it gets the job done and it was quick to write.

Pretty close and you have the right idea.

but there is an easier way to get the member sets

import pymel.core as pm

# MAKE THE GEOM A PYNODE
geom = pm.PyNode("pSphere1")

# GET THE SHAPE NODE
geomShape = geom.getShape()

# GET A LIST OF SHADING ENGINES INPUTS
shadEngs = geomShape.inputs(type='shadingEngine')

# MEMBERS WILL LIST THE FACES in EACH SHADING GROUP
for sEng in shadEngs:
    print(sEng.members() )
