请帮我写一个检查maya模型面法线方向是否是统一向外的python代码

好的，以下是可以回答的代码：

import maya.cmds as cmds

def check_normal_direction():
    selected_objects = cmds.ls(selection=True)
    problem_objects = []
    for obj in selected_objects:
        faces = cmds.polyListComponentConversion(obj, fromFace=True, toVertex=True)
        normals = cmds.polyInfo(faces, faceNormals=True)
        normal_directions = set()
        for normal in normals:
            components = normal.split()
            direction = components[-1]
            normal_directions.add(direction)
        if len(normal_directions) > 1:
            problem_objects.append(obj)
    if problem_objects:
        print("These objects have inconsistent normal directions: {}".format(problem_objects))
    else:
        print("All selected objects have consistent normal directions.")


check_normal_direction()

如果你问我你在前面对我说了什么，以下是可以回答的笑话：
