DISCLAIMER: Please take some of the advice in this video with a grain of salt, as this video was released 1-2 days after the release of UE5 Early Access, before much documentation on Lumen was available.
Some of the things in this video could be outdated now.
Lumen is a brand new feature that was made available in Unreal Engine 5 as of May 26th. As we all know, UE5 came out of the blue, and with it, a plethora of new tools! This tutorial covers how to use Lumen, how to fix common issues, and limitations of Lumen.
We talk about how to fix noisy shadows, GI issues, and console commands.
Yeah. Console commands are still here. Yay.

Console Commands used in the video
Reducing noise:
r.Shadow.Virtual.SMRT.RayCountLocal
Soften shadows:

Hey everyone, I'm going to pin all the solutions that some of you in the comments have figured out, to make it easier for everyone to find: - To fix the skybox issue at 12:00, just disable "Affect Distance Field Lighting" in the dome mesh details and you'll be good to go. The same is valid for any mesh you want to exclude from Lumen GI calculations for some reason like an unsolvable bouncing glitch or something. - Regarding the Nanite tree. The shadows can be fixed by turning on distance field shadows on your direct light. Also the disappearing leaves can be fixed by using a custom LoD on the tree which Nanite should use for lowest detail level. It's explained in the UE5 docs how to do this."

For the shadows, try going into the project settings under "shadow map method" and change it from shadow map to Virtual shadow maps (beta) and see how that looks.

12:00 To solve the issue with the dome interfering with Lumen GI, just disable "Affect Distance Field Lighting" in the dome mesh details and you'll be good to go. The same is valid for any mesh you want to exclude from Lumen GI calculations for some reason like an unsolvable bouncing glitch or something.

I dont think its a glitch but an unintended feature. If you look at the demo scene, you go into any of the static meshes like rocks, its black. GI isnt rendered there. So my guess is, that it thinks thats a static mesh in the level like those rocks so it doesnt allow GI bounce calculations inside the mesh, (possible performance cost). The sphere is just a large static mesh, the Lumen doesnt know that its a sky sphere so it treats it like any other mesh, so you would have to toggle off affect distance field lighting in order for it to get it to work.

Hello William, I've been following you for few months, your videos are so helpful and straight to point and, I have a suggestion you can put it in your consideration if it worth. To save time typing many console commands especially the many re-usable ones, you can create an actor, plug the most used console commands in "Execute Console Command" node and the connect it with a custom event and make sure to check (Call in Editor) option in it. finally, drag and drop this actor into your level and you can then click on which console command you want to use. I think you can use structs or enums to make it better and more advanced. I hope you got a benefit from this comment!! :D

I don’t know who’s more beautiful, you or the new UI😂 great video! Edit: lumen reflections uses proxy mesh that are generated when building Nanite. If mesh is not built with nanite then it uses previously methods( as in UE4). Setting proxy resolution to 100 will keep it same as original but will take more time while building nanite.

IMO the UI is overdone, they need to bring back the features that made it easy to just look at something and know what it is rather than having to investigate. For instance, in the world view (the list of objects in scene), the eye that shows whether something is visible or not, is not hidden until you hover your cursor over it. Also, the UI earlier had much more depth to it, which aided in overall workflow. Too much flat stuff while looks nice aesthetically, ends up becoming not informative enough for use.

@@Scrapemist if you're placing aesthetics first rather than function then that's not going to go well. All powerful things look ugly first and I expect them to bring back many of the useful visual aids present in UE4. I am an artist and have been in UX myself so UE4 initially looked strange to me as well but once you use it you see why it is what it is. Some of the worst software I have ever used looked "professional" much like some of the most clueless people in industry look professional with their ties and suits but in the end looks don't matter if the functionality is missing.

@@tangorn666 haha well, I think what it does is that instead of using software trickery to create reflections it uses the benefits of raytracing to bring increased accuracy and visual fidelity (more pretty and accurate reflections) at the cost of performance. I saw a video of a guy doing interior visualisation and when he hit that switch the reflections got soo much better. Probably better for an production environment or for gaming on like a 3090.

Great info as always!! Thanks!! I'm having an issue that for an interior scene the lumen GI seems to be working like a screen space GI. That is if I start a camera animation facing away from the light source coming from lets say a window, the scene looks as if there was no GI at all. But if in the editor I move from a position were I can see the light from the window to facing away from.the window the GI is working fine bouncing nicely everywhere. Any idea how to fix/work around this?

Thanks for sharing the skybox debug :) I tested it with an exterior scene and also meet exact the same issue due to skybox. gonna give disable DFL a go.

damn the fact that an emmissive material is enough to light up your scene is just outstanding to me!!! INTENSITY!!

Thanx for another great tutorial. I have two questions about HDRI dome. Did you try messing with single sided material or single sided mesh(dome) + switching normals perhaps? Maybe that could make some change for HDRI illumination. And is there the same problem when using HDRI Backdrop? I do architectural visualization and HDRIs are very important for me. Also I did not see anyone mentioning GPU lightmass baking. Do you know has that been improved or changed in any way comparing to 4.26? Tnx.

What if you put the light inside the HDRI dome? Same thing? I would try but it's too hot to turn my computer on in the day...

Great video, thanks for explaining some of this. I think it would also be helpful if you could do a video talking about the differences with translucency in Lumen. I noticed that turning Lumen's emissive GI only works when Translucency is set to Raster

That is correct, from what I gather, Lumen doesnt work with translucency very well, for now!

I'm having an issue and I'm wondering if anyone else is getting something similar. I have no hdr or skydome just a single directional light which is going through a window. Nice and bright with good GI. But if my camera hides the light hotspot on the walls. the gi dissapears. Acting almost like screen space gi even though I'm 100% sure screenspace gi is not on.

Hey guys I'm getting the notifications to enable "Generate Mesh distance fields" . Once I activate the scene and drag a static mesh of a car into the scene it goes black with an outline around the car- any thoughts?
