V-Ray ice material

V-Ray冰材质研究成果，冰的材质有很多种，适用于各种地方，该项冰材质比较适用于冰川、冰洞等大型冰场景经测试
利用电脑配置：

CPU：(英特尔)Intel(R) Core(TM) i7-3930K CPU @ 3.20GHz(3200 Mhz)
内存：16GB
显卡：NVIDIA GeForce GTX 680 (2048MB)

所有单帧渲染时间为：15-25分钟以内
该材质调节并不是太高级别，公布材质面板供各位艺术家参考，如有更好的材质调节，可以一起交流
-----------------
V-ray ice material research results: there are many kinds of ice materials, which are suitable for various places. This ice material is more suitable for large ice scenes like glaciers and ice caves, etc
Use of computer equipment:
CPU :(Intel)Intel(R) Core(TM) i7-3930k CPU @3.20ghz (3200 Mhz)
16 gb memory:
Graphics card: NVIDIA GeForce GTX 680 (2048MB)
All single frame rendering time: within 15-25 minutes
This material adjustment is not too high level. The published material panel is for artists' reference. If there is better material adjustment, we can communicate together

thanks!
