Lumen Irradiance Cache | New Probe Based Lumen For Lower End | Unreal Engine
Added the other day to UE5-Main branch was Lumen Irradiance Cache, which according to the commit is essentially a probe based Lumen for lower end devices. Here I am compaing it to default Hardware Lumen in Crashowary.
You can see that you definitley loose out on alot of finer occlusion details, but overall its still a massive step up vs no lumen at all. Reflections loose out the most here as you can see at the end.
