hi,
i want to fatch two color input value to outcolor but i am getting some error:
i am begginer to python please help!!
import sys ,math

#attributes data
aColor = om.MObject()
aAmbientColor = om.MObject()
aOutputColor = om.MObject()

outputColor = block.outputValue(matte.aOutputColor)
outputColor.setFloatVector(outColor)
block.setClean( plug)
