        Buy the way, i have noticed that bake process using CPU and pagefile too (which in my case was 140 000 GB)
        Please help me understand which memory insuficient in this case.

        increasing TDR delay to 300 solved out of memory issue.

            Hi, I'm Yujiang 'Luoshuang' Wang.
            I have open sourced GPULightmass here: https://github.com/AlanIWBFT/GPULightmass
            With the development of an official GPU Lightmass using DXR starting, GPULightmass is in a frozen state now. Its life is up to you community members!
            Apologies, but can someone clue me into where I can learn more about this official GPU Lightmass development?

                It won't be getting improved as he's no longer working on GPU lightmass. Read the thread.

                He is however working on improving current lightmass and working on a future version. GPULightmass however is open source and nothing to do with him anymore.

                  I used the 4.21 version of this and had a bat file to change quality config. the version of 4.22 I downloaded doesn't have anything like this nor an uninstaller. Help please :_D

I've tried browsing the thread for a result but it's like searching for a needle.

                    Can anyone lend a hand please?
                    Has anyone been able to figure out problems like this where it seems like indirect lighting just doesn't work? Using 4.22.3 and running into this problem with no bounce-lighting on ceilings, on a purely indoor scene with just point and spot lights.

                      Yeah it's bugged in 4.22.3, see https://forums.unrealengine.com/unre...t-node-in-4-22
                      It seems fixed in the current 4.23 beta build (preview 3)

                        Oh god...you're right, I just tested it. Thanks for the link, I would never have figured that out on my own.

                        How did such a massively game-breaking bug not get fixed after three updates...or even get released in the first place...I hope I can cherry-pick that fix commit into 4.22.3 because it's not feasible to upgrade at this point.

                          I'm in the same situation...I don't really know how to backport the fix to 4.22.3...so I'm waiting for Epic to wake up (I don't want to use a beta build for my current professional project)

                          About gpulightmass: anybody knows how to use it in 4.23 preview?

                            Are you using Rect lights?

                              Fix is in 4.23, it's an issue with the material compiler. You're going probably to backport the fix to 4.22.3, it's what we did. If you're not a programmer, you should probably move to 4.23. I'll be very surprised if Epic find time to fix this in 4.22.3 (even if it's basically a copy/past, it's taking no more than 10min), generally they're moving forward and ask to people to update. It shouldn't be dangerous for your project since the big jump was 4.22 rendering wise.

                                I was, but I switched them out for spot lights to see if they were bugged with GPULM.

                                I used git cherry-pick to merge the commit https://github.com/EpicGames/UnrealE...1ccb5575c6d40b into my 4.22.3 build and it seems to work. It looked like it was still broken at first, but it seemed to fix itself after I made some meaningless changes to my material instances and re-saved them. Maybe the material data is cached somewhere and not updated unless it's modified.
