id also love lumen being added as an option, including a hardware raytracing mode too, rather than just software raytracing which seems to be the norm for ue5 games
You cannot just "turn on" Lumen, (well, you can - but it doesnt work exactly like you'd expect) though I'm sure some modders will be doing this if not already. It's definitely cool when enabled, and we're investigating how to allow for people to give Lumen a go while also having regular "baked lighting" for players who don't have supercomputers.
