Unreal Engine 5 Realtime Global Illumination

Showcasing Unreal Engine's "Lumen". It just works™ right out of the box. This is just the basic scene with Starter Content.

That is just outstanding. Can't wait to dive in!

Image the next gen games! The Unreal 5 reveals are the same as when I first saw Crysis and the Cry-Engine. This is truly next gen and can't wait to see what companies would do with this.

Wow crazy how delayed the GI calculation is, but they managed to make it look really smooth

Accidentally saw this and instantly thought of the long hours with Mental Ray 20 years ago. You'd have to wait at least 15 minutes for a decent but still low quality image with ambient occlusion and GI.

Very enjoyable to watch - would be better if the eye-adaptation was disabled though.

I was pleasantly surprised by how it all just works.
Got a GTX 1080 and expected not to run the demo at all, i got 24 FPS in-engine which to me is pretty good for an old 1080.

And the lighting, thank god I don't have to worry about baking lights anymore!

i've been playing with the gi for an hour, can't believe how well made this was implemented, quite sad we've been asked for this since 4.06 and we finally got it in UE5

Still some delay in the ray calculations but faster than anything I've seen.

What? what before this?make this so hype?what the different?

[Maxmax]

Does anyone know how does this compare to the ray tracing technology of 4A Games used for Metro Exodus Enhanced?

[agastyavalisetty]

i tried the same with blender evee and I closed the thing shut and it was still brightly illuminated

[sikliztailbunch]

In case of you want to prerender a scene. Say, for example for film production. Can you turn off the delay and set it to gather all light before rendering? I understand that the delay is still inevitable for realtime for obvious reasons

[yenkule]

Dose this mean we dont need to bake light anymore? Just put assets and done?

[SanOcelotl]

how expensive is lumen compared to ray tracing?

[Basman]

I heard somewhere that you can get real life graphics using only 1080p. Is that real? Because if it is... It will be a game changer!

[TGADB]

Hows the performance compared to Old VXGI and RTXGI frm Nvidia s end??

Sometimes, I feel like things from Nvidia packs with speed, it's a feeling thou thats why i am asking straight

[sculptor]

is this using the GPUs raytracing pr is it software?

[fabbrobbaf]

Is the GI actually real time or is it slightly delayed?

[davinderrehal]

Godot implementation is way better than this
