Emissive Color will Affect the Environment

Dear Community,

I recently still struggle with the problem of the emissive color that will affect the environment.

In UE4, when I set up the emissive color and apply it to the object, it will not affect the environment like in the picture below.

But when set up the same in UE5, the emissive color will affect the environment like in the picture below. Is there any way to disable this?

Thanks for your help

Usually, it’s what people want :slight_smile:

You could turn off Lumen, I guess?

You might also be able to fix it with a change in the material, although this seems to differ between engine versions.

Thanks for your quick reply. Is there any way to disable this while enabling Lumen?

May I ask how to do this in UE 5.1? Is there any tutorial?

This material should do it

The custom node is

However, if your emissive is anything other than 1, you will still get the screen probe picking up stuff. You can turn off with the console command

r.Lumen.ScreenProbeGather.ScreenTraces 0
