hey Guys,
i m trying to get the color node incoming connection so that i can store
it for later use,
ever thing works well before for loop but when i run for loop to chk the
type then it give me error :
# Traceback (most recent call last):
# File "<string>", line 12, in <module>
# File "<string>", line 17, in <module>
# TypeError: 'NoneType' object is not iterable
and i have no idea how to fix it, please help.
thanks a lot.
have a good weekend. :)
import maya.cmds as cmds
# getting the shape node from transform node
selectedObj = cmds.ls(sl = True )[0]
selectType = cmds.listRelatives( selectedObj, shapes = True )
#getting the name of shader connected to it
listConnect = cmds.listConnections(selectType, type="shadingEngine")[0]
shadername = (listConnect + ".surfaceShader")
shader = cmds.listConnections(shadername)[0]
colorAttribute = (shader+".color")
colorValues = cmds.getAttr(colorAttribute)
print colorValues
inputConnectionCheck = cmds.listConnections(colorAttribute,destination =
True)
print inputConnectionCheck
for incoming in inputConnectionCheck:
if cmds.objectType( incoming, isType='file'):
filePath = cmds.getAttr(incoming+".fileTextureName")
print filePath
else:
colorValues = cmds.getAttr(colorAttribute)
RGBvalues = colorValues[0]
redValue = RGBvalues[0]
greenValue = RGBvalues[1]
blueValue = RGBvalues[2]
print (redValue, greenValue, blueValue)
