Possible to Use Animated Sprite Material?

[ForestEco]

I tried using an animated sprite material instance, so it is created by calculated frames (see screen capture), but it remains still or moves very briefly in the throbber. Is there a way to make that work or I need another approach?

It would also be nice to be able to move the sprite or image along the bottom of the horizontal box. Is that possible as it is or do you have to make an animation that is to scale of the screen?

Unfortunately, you can't use material during hard level loading using Open Level node
