Warning: My english is very bad!!
I dont know a Tutorial.
But you can do the follow:
If you have Maya(PLE) or something, make a little animation with it.
Then render the Scene as image sequenz.
Then. Open Photoshop and make a TGA File with, for example, 120 high and 1600 width. (one Image has 160 x 120)
Then place every single image in the large TGA File.
I hope this is what you want to know.
