Maya导出FBX后，FBX导入UE4的材质顺序

参考连接：Solved: Manage materials order - Autodesk Community - Maya

objMaterials = []

objs = cmds.ls(sl=True)
allFaces = cmds.polyEvaluate(objs,f=True)
for obj in objs:
      print faces
      for face in range(allFaces):
          #print face
          iteFace = obj+".f["+str(face)+"]"
          print(iteFace)
          cmds.select(iteFace)
          cmds.hyperShade(smn=True)
          material = cmds.ls(sl=True)
          #print material[0]
          if not material[0] in objMaterials:
              objMaterials.append(material[0])

注意：如果物体面数多，速度会有点慢
