The color of the vehicle has been modified, but the simulator shows the same color as before. Why

def main():
client = carla.Client('localhost', 2000)
client.set_timeout(2.0)
world = client.get_world()
spectator = world.get_spectator()

# 获取特定车辆的蓝图（Audi e-tron）
specific_vehicle_blueprint = world.get_blueprint_library().find('vehicle.audi.etron')

# 设置车辆颜色为白色 (R, G, B)
specific_vehicle_blueprint.set_attribute('color', '255, 255, 255')  # 白色
print(f"Set color to: {specific_vehicle_blueprint.get_attribute('color')}")  # >>Set color to: ActorAttribute(id=color,type=Color,value=Color(255,255,255,255))
# 随机选择一个车辆的初始位置
location = random.choice(world.get_map().get_spawn_points()).location

# 使用特定车辆蓝图生成车辆
transform = carla.Transform(location)
vehicle = world.spawn_actor(specific_vehicle_blueprint, transform)

This may be because the material slot is not named "Bodywork_Mat", see #7611
