BPW Character Widget correction requested


I am going through the tutorial

Unreal Futures: Careers in Animation | Course

At 3:00 the instructor finds a magical BPW_PrepCharacter widget, but does not explain how to write one. If this is used to correct errors in layering FK controls over imported animation, we do need to understand how to write one for our own animations. Has Unreal 5 corrected this issue otherwise, or must we find a way to recreate this widget?

I am experiencing the same issue with my own character. Does anyone have information as to how to create this widget?

I am unable to assign this course to students as is.

Many thanks
