Texture animation (nodes) for unity, Question

Dear Amazing blender artists,

I’m making tis tiny little game to learn the general gamedevelopment skills.
Using Qubicle I made a little character and imported it as an OBJ into blender.
My goal is to animate a blink and import the entire model into unity for idling and so on.
However nothing is happening. And the textures look blurry no matter which settings I use.
My blend file: :wink:

Very Kind Regards,
Cedric
