Hello there ,
i would like to ask how can i import , or use the character ( the blue one on the website on the unreal manual , or the yellow one of the tutorial ) .
Because i dont want right know to loose much time doing animation and only focus on gameplay
You can open any example, go to the specific content, right click the content and select migrate, and pick your game project. Using migrate copies all the required items, to your project.
When you already have the character in a anim/char bp, then you can do it with the migration tool -> the way that unit23 mentioned
