My first meet with Unreal Engine 5 for Archviz. Lumen is amazing and saves a lot of time. It is an excellent alternative to raytracing on increasingly expensive RTX cards. This scene was directly imported from 3ds max without unwrapping so a lot of time that I saved, in addition, no light building.
But in the end I will use Lumen for the static renderings instead of Vray or Corona but For an interactive scene I prefer the method with light building which allows to gain in fps.
