Agreed. Fantastic video

[@12345ches]

To get rid of the noise, you can increase the screen percentage number in the viewport settings (top left corner), to 200. Although it does have a big impact; I would only use it to take some still photos.

[@VRDivision]

Great comment, thank you so much!

[@BoomerNate]

@@VRDivision The Unreal produced videos I've watched on Lumen suggest that the artifacts you're seeing in the shadows around the 9:40 mark in the video are due to software ray traced results since you're using a 1080TI. RT capable cards should generate much cleaner results.

[@09spidy]

The fact that you're getting real time Global Illumination at 30-60 fps on a 1080Ti is incredible, Lumen is really magical.

[@VRDivision]

I know right!

[@PrefoX]

ya that card is ancient in terms of raytracing. 3090 should be 10 times faster

I just got into using unreal engine for my render and my god it's beyond anything I have ever used its quite literally breathtaking

[@nemysisretrogaming3771]

From the limited time I've looked at UE5 it seems that any geometry that is exposed to both interior and exterior lighting using lumen should be closed, fully modelled geometry. If there's no transparency in the mesh then convert it to nanite mesh and that mitigates the old problem of too many triangles hence the reason the geometry was left open in the first place to reduce graphic engine costs.

[@VRDivision]

I think that's a great comment, I agree on closing the geo

[@apixel.content]

Thanks for awesome video and UE tips!

[@Roozy_Persepolis]

at 9:22 , you can go to your project settings and enable Use Hardware Ray Tracing. ,you can also go to your details panel and increase Lumen Reflections quality

[@Dante02d12]

Best video about Lumen so far! It's a shame it doesn't work with VR yet. Have you tried it actually? What does it do if you use Lumen in a VR project? I hope they'll make it quick, along with Nanite!

[@3pcgi959]

This is a game changer!

[@NicolasDussartFathom45]

As we didn't need anymore to cut objects in order to unwrap them for baking, to solve the light leaks just model with thickness and as one asset only a house/appartment. I tried that method and it seems to work just fine for now.

The weird shadow stuff might be that you need to increase the real time real tracing samples from 1 to higher but not to high cause that effects performance. I believe its in the PP volume.

Hi and thank you for this great video. I`m trying Unreal engine 5 too but I have a problem and don`t know what`s causing it. After setting up the lights , global ilumination it`s not working as it should. When I look at the light that is hitting the floor, GI is working, but when I change the view to the ceiling for example, and I can`t see the light that is hitting the floor, GI dissapears. Anywhere I look in the scene, where I can`t see the light hitting the mesh, I can`t see the GI . It`s like it`s getting deactivated. Is there any light cache that I need to enable ? Thank you!

Sir. Im using sketchUp software. If I import it in UE5 do i need to UV unwrapped all model so i can edit each material on it? Or UE5 automatically UV unwrapped my model? This is what i did in UE4 before. from skp > 3ds (unwrapped all materials) > UE4 (I can edit my material and has a accurate scaling)

[@rob19632]

this is amazing I just whish you could import real lighting data into unreal engine because programs like Relux and Dial lux take hours just to render 1 scene. This is because they run the render on CPU and not GPU . If you could define lights in Unreal using IES or LDT files then that would be great. Industry needs to work with the gaming industry.

[@VRDivision]

Didn't really understand

[@antoncromas5125]

Directional light and skylight works great even in the UE4. The problems arise when you cannot use directional light and skylight like for a photography set for example. Using just the regular lights the lighting still looks pretty bad for real time with a lot of shadow artifacts and flickering (without any modding of the .ini file) When following the UE5 development I was kind of hoping the realtime viewport will look somewhat close to the traditional render engines.

[@starfoxnik7770]

I confess i was a little disappointed too. Sometimes there are so many shadowing artifacts and ghosting. For me it isnt viable at the moment. But hey it´s early access they have a lot of time to polish lumen.

[@VRDivision]

You make a great point Anton, I also agree with STARFOXNIK, I hope we get exponential improvements in lighting, I was watching some tutorials on cinematic lighting in real life and hope to keep learning how to achieve better lighting with more R&D and modding
