The problem with this video is that as a newcomer to UE5, THIS video is the FIRST thing that you encounter in the learning section, and while it’s very neat as a tech demo I quickly got lost and gave up trying to learn any practical skills. That said, I did somewhat understand the types of tools available and understanding what is available is the first step in learning it.
I’m going to continue exploring the learning library for what looks like much better practical videos for beginners, but I highly recommend anyone else new who is watching this to NOT try and follow along in UE5 past the lighting and cubegrid stuff, since the rest is dense and skipped over anyway. DO watch it, however, so you know what you can research later once you need it.
