How do I create an animated texture?

I’d like to create a simple animated texture, like a flip-book style animation that just rapidly changes between whole images.

But I can’t find any option to allow this. I’ve never done much with materials in Unity beyond selecting a different diffuse maps. I don’t even know where to start looking.

You need to modify the U,V coordinates of the material using SetTextureOffset.

I have to write code and create a script that does it? There’s no functionality built-in to Unity?
