              And here's my UE4 fork with GPU Lightmass cherry-picked from Yujiang's code on top of 4.23:

              Hope you guys find it helpful!
              Doesn't exist anymore. Searched for it in github didn't find it. Just FYI.
              BTW, I installed the 'binary' version where you just copy over to engine DiR,4.23 here.Not sure how to uninstall, would like to as I don' see it working nor any place noted where to uninstall.

                It's well past time this was part of ue4, the speed difference is enormous.

                      Hi. I have been using this to compute lighting in Unreal since 4.19 it has always produced very good results, perhaps even better than CPU lightmass. However, since upgrading to the 4.24 version, I've been experiencing problems with it. Sometimes, GPU lightmass neglects objects from the light calculations, particularly small meshes. As a result, these meshes end up being pitch black after baking the lighting. I've attached an example below:

                      https://imgur.com/a/a8iHexk

                      Is there something I can do on my end to fix this or is this a bug with GPU Lightmass?

                      Thanks,
                      Goolog

                          Yes, and I see nearly NO GPU use, MAX so far I've seen is 5%>GTX 9502gb, yes I know I need to upgrade but my i5-3570 is hanging.
                          I also can't FIND the 'uninstall' location to get rid of it,,again, anyone know where it is/how to manually do it if need be ?

                          Thx

                            To see the gpu usage, you need to select "cuda" in the dropdown menu on one of the gpu graphs in task manager/performance.

                            To uninstall gpu lightmass, from the readme:

                            " Reverting to CPU Lightmass

                            The safest way to revert back to the standard CPU Lightmass is to open the Epic Games Launcher and click on the Verify button under the engine version.
                            "

                              HM ok thx on reverting, I misread it earlier, and to cuda,don't have it anywhere, I thought it was built-in to nvidia driver, thought Id seen someone on forum also mention that.

                                Hey guys! Does anybody know why after my GPU Lightmass bake I don't have proper volumetric lightmap? Probes are just black... I'm using spotlight and emissive light in the scene.. Thanks a lot!
