I see that what you need is "Custom Item Texture" and what Animatica advertises is "animated texture format", I just question if there is overlap there. I know MCPatcher offers alot of things so I could just be mixing things up.

Of course not. Custom Item Texture and Animated Texture Format are two different features.

Figured as much. I really need to look into all the individual features MC Patcher adds. It's hard to keep up. >.<
