写一个blender的python脚本 blender 给场景中的立方体加上中国国旗贴图

import bpy

# 加载国旗贴图
flag_texture = bpy.data.images.load("path_to_china_flag.png")

# 获取场景中的所有立方体对象
cubes = [obj for obj in bpy.context.scene.objects if obj.type == 'MESH' and obj.data.name == "Cube"]

# 遍历所有立方体对象，给它们添加国旗贴图
for cube in cubes:
# 创建材质
mat = bpy.data.materials.new(name="FlagMaterial")
mat.use_nodes = True
nodes = mat.node_tree.nodes
links = mat.node_tree.links

# 获取 Principled BSDF 节点
principled_bsdf = nodes.get("Principled BSDF")

# 创建 Image Texture 节点，并设置国旗贴图
image_texture = nodes.new(type="ShaderNodeTexImage")
image_texture.image = flag_texture

# 将 Image Texture 节点输出连接到 Principled BSDF 节点的 Base Color 输入
links.new(image_texture.outputs[0], principled_bsdf.inputs[0])

# 将材质分配给立方体对象的所有面
for face in cube.data.polygons:
face.material_index = 0
cube.data.materials.append(mat)
