Why can't I animate texture offset?

Unity 4.6.1f1, Pro, Android Build

I’m animating my ‘x offset’ from (0 to -.5), I can see the numbers changing when it plays, but everything is in red and nothing is visually changing.

The UVs are also definitely in the right place, I changed the offset manually without animating it and it works as intended.

This has definitely happened before on other projects. I’m also seeing that a bunch of other people are running into this too, but there’s no solution.

Got it, the Mobile/Unlit shader doesn’t support being animated.
I switched to Unlit/Transparent Cutout instead and it works!
