Hi Mondune! First of all, thank you so much for pointing this out.
You are correct that it was an intentional design. When I first created this asset, the animation was designed to naturally exceed the top edge of the screen.
As you might already know, if you set the UI anchor to the top, it will render exactly as intended without looking awkwardly cropped. However, I figured it might be a hassle to set this up manually in Unreal every time, so I went ahead and created and uploaded a dedicated Unreal Engine version that works perfectly right out of the box, just like in Unity.
Existing users of the Animated Pixel Magic Book, and especially those who purchased the bundle resources, can now download this Unreal version of the Magic Book. This version is set up using frame-by-frame animation Blueprint logic instead of a flipbook.
I wanted to help you out as quickly as possible based on your feedback, so I hurried to put this setup together. I'm leaving a test video here for your reference
Also, your feedback makes a lot of sense! For my future pixel book UIs, I will definitely consider designing them so they stay perfectly within the screen from the start.
Your feedback is highly informative, and I will definitely use it as a reference for my future projects.
