You must have a separate material, which has texture which you want to animate and put in the mesh where you want to animate the texture. You then create a Texture Animation in magos. Then you go to Material Manager and choose material, then material layer which will be animated and in the new windows you choose Animated Texture ID you created. Go again to Texture Animation Manager, choose translation (I guess) and try to write animation keys by hand, try to guess, considering first number is time and those 3 in braces are coordinates.
