alt Hacker NewsYeah but afair UE5 Nanite + Lumen + Megalights + whatever is meant to work together, you can't just replace or turn off one of them without it affecting the others.
So your choices are to tweak the defaults (which are not bad, but generic and the same as everybody else's), or rebuild the whole renderer (like ARC raiders did for example)
You can mix and match to some extent, though Nanite, Lumen and Megalights are intended to work together. Megalights really needs Lumen, and Lumen works best with Nanite.
There’s the whole forward renderer path you can use instead, which works well on lighter hardware. Or you can use baked lighting instead of Lumen, and some people have created other realtime GI systems as plugins.
You can’t really change the material-shader pipeline though without overhauling the entire engine.
There are also a ton of parameters and configuration options you can change. These can be quite obscure and this is where small studios struggle.
