There one sided polies so unless gg can do two sided textures then no. Two sided textures use to be used allot in games, but people now days claim its slower than using two sided polies. I really dont see how more polies is faster at loading, but they claim its lets draw calls or something so ....
One example of two sided textures used in a game allot was Vampire The Masquerade. I use to skin that game all the time and 2 sided textures made it great for creating rips in cloaks etc.
