      The only thing Epic said was it wouldn't be easy to implement.

          So one talented user "Luoshuang" has implemented a working GPU lightmass baker into UE4 and all epic has said about this... it wouldn't be easy to implement ?
          Thats kinda a disappointing statement from epic, i have to say.

            Great job Luoshuang, do you have a tip jar? Here is a scene rendered in GPU Lightmass in 33 minutes; Production quality with quality turned up took 2 hours on a 6700K.
            Ryzen 9 3950X / 64GB DDR4 / EVGA RTX 2080 Ti / Sketchup Pro / Substance Designer and Source / Unreal Studio / Twinmotion

              GPU Lightmass (4.19.1) causes some problems with this scene ( dark upper area and some sparks on the ceiling ):


              Below the reference CPU baked (4.18.3):

                Hello, I was so excited reading this topic, I have downloaded Dropbox hi-quality and placed it to C:\Program files\ Epic \ UE 4.19 \ Engine and replaced the files, then I've opened my archviz scene and tried to bake it, but once its completed BVH it's giving these errors. I started clean with full restarting PC, on Nvidia 1080, Windows 10. 32GB Ram

                P.S. My TDR was set to 60 for Substance Painter, I also do not have D:\gpulightmass folder and never had it. The only thing that broke is the plugin C4DtoUE4, which broke all materials, but I did not use them because all mats in the level were replaced to UE4 mats.

                P.P.S: I do not have any unique lights, only regular lights with IES set as Static. Skylight and few lightportals. I did not use any Vray or Unreal Studio. Only the plugin, it shows the errors with mats, I click Ok and usually worked, but not in this case.

                  ...I had crashes with only one scene having non "standard" lights in it... (vray scene, Unreal Studio with converted lights!)

                      Please hire "Luoshuang" in your company
                      he can improve the lighting quality for us

                      for my scene
                      cpu render time 6 hour - i3 4130
                      gpu render time 18 minute - gtx 1060

                      my gpu is nvidia T but why this gpu renderer doesnt support amd ?
                      ocrane is gpu renderer and support amd - also blender cycles !

                        Makigirl - I have to say that I always use 2 sided material.

                          Out of memory. But my scene is very little only one room and couple stufs. gtx 650 ti 1gb. fx 6300 maybe more good than 650 ti

                            Didnt Luoshuang have an internship at Epic already? Thats when he built the multibounce skylight if I remember correctly^^

                              Hi Luoshuang,

                              Thank you so much for sharing this with us.
                              Just ran a few tests and it works great.
                              I have never been happier with the GI quality in unreal !!!!
                              And the speed... **** its fast
