that makes me mad,
its so obvious he is lying, and he added the original render screenshots into Maya using photoshop(it says the first one was rendered in 3 seconds, quite a mistake, lol)
also it is distorted horizontally, and Maya doesn't do this, it changes the size in both dimensions equally.
quite a few obvious mistakes ^_^

does the real creator know about this?
