Rather it is a different kind of scolling texture function. It will move the texture by a factor set in data0 and at a rate set by data1. Important to note data0 must be at least 4, not totally sure why but any less and it won't do anything and if it is 0 it crashed the game with a windows error.
In the example video (sorry for choppiness) the first model is a landing pad I had made using scrolling texture, the next version is using the animated flag with a data0 = 80 and a data1 = 6
the box in the middle is using the same numbers and is there to show what is really happening to the texture.
Now what is it good for? Well you can make colorful changing lights on a console, I believe the hoth_prop_command_console_a and _c use this flag.
But now here is the video.
