I know, but this is showcasing some new lighting or something? And I think the lighting in the Matrix demo is more realistic.
Nope, it's confusing, but this is
not showcasing some new lighting. This is just new ways to use general lighting systems in the MetaHuman creator. (Basically what happened is that Unreal reached out to a professional filmmaker and had him rig some very specific lighting pre-sets that mimic common cinematic lighting approaches. If you would like to know more, you can read the
UE blog entry on this subject.)
It's not even necessarily tied to UE5's Lumen, since MetaHuman can build for the previous version of Unreal Engine. (So, that's another reason why this is misleading, as the CramGaming article posted is off-base about MetaHuman being a "Unreal Engine 5 Metahuman new lighting demo video".) These MetaHuman lighting pre-sets are available in the development tools for UE 4.26 & 4.27.
(I didn't watch the whole video, but it looks like they have on the lighting system "Epic (Ray Traced)", which I believe would not be UE5 Lumen. Not sure if there is a Lumen toggle in MetaHuman Creator yet?)
...It basically has nothing to do with what you, as a gamer, will play on your console. This is pretty much strictly for developers.
And as far as the Matrix demo, The Matrix Awakened is made by developers using the technology we're talking about, plus more technology made for the game (and UE5 as the running engine.) It looks better to you because it's got more to it, and because it's done.
So, if you're interested in the ingredients and process, then sure, take a look at this stuff and learn how your games are made. However, this stuff isn't for people who mainly interested in what is awesome that you can see and play for yourself on your home console/PC, or people who are looking for demos of the next-big-thing that will be playable for you eventually. This here is not UE5 cool-shit tech for us gamers.
