    I got a question. What is the approach for foliage and tree's leaves? On GPU the leaves' shadows are completely static, while on CPU you can see them moving. Is there any workaround for that or is just a limitation for now?

      Hello everybody...

      My problem is, after I started bake my scene with 4.20.1 GPU, skylight does not affect the upper floor of the apartment. When I change the intensity the lower floor takes all the light effect immidiately. I can see the reflection on the floor is changing. But there is completely no such effect on the upper floor. It is very interesting...

        Skylight resolution is vastly increased and there is experimental 'explicit skylight sampling', as a result the shadows will be even sharper - not very sure whether you guys are gonna like this...
        I think it looks awesome =D

          I like it, more detail is a plus generally.

              Looks good. But not sure if properly testing the setup for Lightmass: are you sure you are using static lights? Much of the light, especially the shadows coming from the windows are behaving more like Cascade Shadow Maps than static shadows. They are super sharp and unrealistic for the scene you seem to be after. I mean, the light coming from a static directional light should have some smoothness and be baked, but it doesn't look like it on your scene (that could be a result of Luoshuang's experimental features, so that's why I'm asking).
              Also, to have that kind of sharpness projected to the meshes you would need super high lightmap resolutions on most of them, which I imagine 6GB on 1060 would not be able to handle. Some objects seem not grounded, especially transparent objects.

                  I can't run GPU Lightmass in 4.20.1 but have had zero issues with 4.18 and 4.19

                  I constantly get the error:

                  Unspecified Launch Failure

                  Any advice would be appreciated! It's the exact same project as I used GPU Lightmass on in 4.19, brought over to 4.20.

                  I even created a new project, and tried to build the default map, but got the same error.

                  Thanks!

                    Unfortunately I have the same error... :-(

                    EDIT: Reinstalled Nvidia Drivers to 398.82 and everything is working fine. Thanks Luoshuang :-)

                      I have a problem with my scene when i bake(4.19 or 4.20)
                      it's a new problem for me, because 2 days ago i didnt have this problem.
                      i did just add lot of assets (230 assets) into my scene, and now ue4 doesnt bake, when i remove some assets, baking works
                      I have 3600 asset/actors into my scene(cut by level)
                      any help is appreciate

                        I reinstalled my drivers too. K let me wipe the drivers clean then try again.

                          Hey Luoshuang just ran DDU on my drivers and reinstalled, no joy. Any insight into the error I'm getting? Thanks!

                            Any news about Sparse Volumetric Light Samples on 4.20?

                              Arghhh I also desperately need them!

                                Try to make Directional light as stationary.
