here is a few function that should get you going:in short, you create a
shader and a shading group, connect the shader to the shading group
Then connecting an object or polygon face(s) to the set will assign the
shader to the objects/faces
good luck
import maya.cmds as mc
""" create a new shader """
def createShader(shaderType='lambert', name=''):
if name == '':
name = shaderType
name = mc.shadingNode(shaderType, asShader=True, name=name)
sg = mc.sets(renderable=True, noSurfaceShader=True, empty=True, name='%sSG'
%(name))
# connect shader to SG
shaderOutput = 'outValue'
if shaderType== 'mia_material' or shaderType == 'mia_material_x':
if shaderType == 'mia_material_x':
shaderOutput = "result";
mc.connectAttr('%s.%s' %(name,shaderOutput), '%s.miMaterialShader' %(sg),
force=True)
mc.connectAttr('%s.%s' %(name,shaderOutput), '%s.miShadowShader' %(sg),
force=True)
mc.connectAttr('%s.%s' %(name,shaderOutput), '%s.miPhotonShader' %(sg),
force=True)
else:
mc.connectAttr('%s.outColor' %(name), '%s.surfaceShader' %(sg), force=True)
return [name, sg]
def assignToShader(shaderSG=None, objects=None):
# assign selection to the shader
if objects is None:
objects = mc.ls(sl=True, l=True)
for i in objects:
print i
try:
mc.sets(i, e=True, forceElement=shaderSG)
except:
pass
"""
Example:
# run the next line
shader, shaderSG = createShader('blinn', 'foobar')
# SELECT SOME OBJECTS
# run the next line to assign the selected object to the shader
assignToShader(shaderSG)

They say, "Evil prevails when good men fail to act." What they ought to say
is, "Evil prevails."
