UMG allows you for handling and animating the user interface. You could animate a logo coming together if you prepare the elements in advance, include text, you can also use materials.
Here’s a primer: Basic UMG UI Animation - #48 Unreal Engine 4 Beginner Tutorial Series - YouTube
also, can’t recommend this gentleman enough:
You might not be find an in-depth tutorial about creating animated logos as the UMG designer is not really meant for that. That does not mean it cannot be done, though.
For a simple logo text coming together letter by letter, you would prepare a text block for every letter and slide it into position by shifting it in the canvas panel.
I’d be happy to chip in if you briefly describe what you want to achieve.
