Please Epic make the “Skylight Radiosity” pass on the Swarm distributed along all agents, everyone is doing it on their own in full, so it’s calculated x clients redundantly.
I’m aware that the amount of calculations is directly linked to the “Num Sky Lightning Bounces” in World Settings, recently introduced in 4.18, but I don’t want to lower it under 10, good light is very important for my architecture, design and automobile projects.
Right now with 5 x 32core swarm agents, Radiosity takes over 50% of my Light baking time on “Production”. It would be around 10% if it were distributed, cutting my Light baking time by whopping 40%.On “Preview” it’s about 80% of the time.
So please let it distribute, share it between clients, then go on to processing mappings. All architecture guys will love you for it.
Occasionally I experience swarm agents bailing out from processing mapping and restarting with radiosity (see attachment, the 4th agent started with rad again then wiped it on render end)
