Animated texture of models

Hello, i have 256 x 256 character texture, face and body.

I want to animate the body texture, changing the textures upon various moment in game.
How do i accomplish this?
I am not talking about movies or cutscenes, but in game, battle scenes or attacks.
I know about blendshapes or bone animations, but my model is rather lowpoly, 1500- 2000 tris or so.
So, there’s not much bones, but maybe, layered textures, frame by frame.
And i don’t know how.

hi. while enquiring one animated assets, i found about the flip book node for materials. did you tries this?
