这是一个不错的3D建模软件，在编辑框里可以类似像maya一样随意拖动模型，可以加纹理、雾化效果等等，当然还能保存数据，可以供为 3D游戏开发美工作模型设计工具！强烈推荐！-This is a good 3D modeling software. Message editorial maya be the same as similar random drive models can be increased texture, atomizing effect, and so on. Of course can preserve data, for the development of 3D games for the U.S. working model design tool! Strongly recommended!
