What is the maximum resolution of the generator? Can it make large textures? (2048x1024 and/or 4096x2048)?
Also, it seems very similar to the Photoshop plugin LunarCell hich also makes textures and clouds at any resolution you need. It's truly a device for the lazy. If you really want to make good textures, make them yourself, combine and mix, I always get good results when I create my own texture. I use it primarily to make wallpapers and Space Art, not for use in models or games like GalCiv2, . Although when I do use them in Galciv2, the textures look pretty nice.
