Viewport mode "Lightmap density" bug

Wisewalker · February 29, 2024, 4:15pm

Hello! I have recently started using UE 5.2.1 and faced this kind of problem. I didn’t change neither any options of the project nor options of the editor. It’s default 3d-person project.

Switching on “Lightmap Density” mode and moving through the level on the viewport gives these results. (I found information about disabling options “Instancing Stereo” and “Mobile HDR”, but it didn’t help).

Running it with these system and technical characteristics:
OS: Windows 10 Pro 22H2
GPU: Nvidia RTX 4070 Super
CPU: Intel core i5-13600K
RAM: 32Gb

Could you, please, give an advice how to solve this bug

Update to 5.3

It is not fixable on this version at all?
I’m just not sure that the latest version will go well with my configuration considering the new features on it

There’s a fix for 5.1 you may be able to adapt to 5.2: UE5 Lightmap Density artefacts and issues with baked lighting - #4 by LukeTinyT

If you get a 404, you need to link your Epic account to your Github account.
