Been asked a few times lately about using animated textures on a rig and how to control those textures. Like with most things in Maya there are a bunch of ways to do this . . . you could apply different textures to duplicates of geometry and literally swap geo for any given frame of texture you want, but that's a) a pain to set up and b) kinda like shooting a fly with bazooka. Heavier in your scene and more a pain to deal with. Instead, in this vid I'll go over a couple of different ways to use the ".frameExtension" of an image sequence to control what shows up as our texture. I also briefly discuss a more complicated way of doing the same thing using nuke and UV maps, which I covered in another tutorial.
BTW, I talk about using this on a face in the video, but you could obviously use this on any kind of shader connection for any part of an object. Faces are just the most obvious. . .
