Need help with importing stage texture animations.

[TheFirstZero]

Hey guys, I know about replacing models in stages but I have no clue how to swap texture animations.
I want to put this stage's background (http://forums.kc-mm.com/Gallery/BrawlView.php?Number=32013) on this stage (http://forums.kc-mm.com/Gallery/BrawlView.php?Number=31205)
I have properly imported the models of the background but I cannot get the clouds to animate.
I import the texture animation but for some reason in-game it won't animate.
I've seen no tutorials or videos talking about texture animations or how to link them with textures/models.

BAM!! Tutorial on swapping a background. Little old but basics still apply.
