Loving this, as for .txis, I don't have much experience but they can be used to animate for definite. Make the targa with each frame of the animation next to each other, like a gif but in the same layer, and then the txi is used to choose which one is used and how quickly they change. Just have a look at one and work it out, they're not big files, shouldn't be too hard.
