How do I disable Lumen in my 5 project

Hello,
I’ve been looking all over the place on how to disable Lumen in project settings in my 5.1.1 VR Quest 2 project.

It is greyed out in project settings under global illumination. I’m pretty sure it is killing my FPS.

Thanks

Arthur

It might be the beta shadow map thing.
Go to project settings and type in shadow maps and make sure you aren’t using the beta.

Edit: And, while you are at it, you can probably just go straight down the rendering section and turn everything off. That has to help at least some.

Hi Detach,
The shadow map thing is greyed out too. There’s a bunch of stuff greyed out that I can’t change.

If I set r.DynamicGlobalIlluminationMethod from the command line and then package the project will that turn it off for the packaged game or is that jus for when I’m in the editor?

Thanks

Hello @VictorLerp,

I hope you don’t mind me bothering you. I saw you mentioned in another post about this issue.

I’m trying to turn Lumen off in my Unreal 5 project since my FPS is in the gutter. Do you know how I can do this?

I turned it off with the console command and packaged up the project but saw no change in my quest 2.

Thanks

I don’t know why your project settings are greyed out, but if you want to use a console command to fix it, you might be able to use the “execute console command” node in blueprint begin play (I’m not sure what the C++ equivalent is).

Any console commands you just type into the editor are not permanent, so they won’t carry over to a build or even after you close the editor. But, if you put it in a blueprint, that should fire it every time for you. The thing about that though, I’m not sure if that node is “supposed” to be used in a finished game. It might just be a development-type node.

When Lumen is greyed out in Project Settings, it’s because it’s not supported with your current project configuration. In this case, I know it’s because you have the Forward Renderer enabled, and Lumen doesn’t work w. Forward. Lumen is also not supported on Oculus Quest, and as such is not the reason for your performance issues.

Yes. The same thing. There is no option to disable Lumen in a VR project. It`s greyed out.
