    I'm pretty sure you can achieve the same by raising FireflyClampingThreshold to something like 10000.0 in BaseLightmass.ini

      Someone could provide me links for 4.22 preview 7?
      I cannot find it :O

      EDIT: FOUND IT
      Leaving the link for others: https://dl.orangedox.com/rVuVzbmWWylmlPGbZo

        I've been doing some tests with GPULightmass lately, and am really excited about it. However, I'm stuck in the middle of a hardware purchasing dilemma. Right now the only Nvidia GPU I have is a 1050ti 4GB. I am currently running a Ryzen 7 1700 @ 3.6 Ghz, and when baking lights using normal Lightmass it seems to be 3-4 times faster than GPULightmass on the 1050ti. This is with roughly equivalent settings (preview lighting on the CPU baker and the 'fast preview' setting on GPULightmass). I understand that the 1050ti is not the strongest GPU in the world.

        I'd like to run a series of benchmarks to determine whether I should spend my money on a better GPU for light baking or a second box to route swarm to.

        However, I'm not sure if there's a 1:1 relationship between regular Lightmass quality levels and GPULightmass quality levels. Also, If I put my results into a spreadsheet, would people think about adding to them? This would help me determine which GPU to buy, if that's what I decide on, and maybe help the community too.

          Hey Guys, got this error when trying to build on 4.22 the new Prometheus ,
          I am running a geforce 2080 Ti and my driver is the 419.17.
          I already try to clean the cache in Swarm agent.
          Do you have experienced this error before?
          The GPU Lightmass on 4.21 is working very good.

            Yup, same error too, materialarray at 0 ?

              I think so, NumMaterialElements > 0, is this what you mean?

                LegendreVR @Bakikibakibabaki I've uploaded 0.2.2. See whether that resolves your issue.

                  Thank you Loushuang,
                  Errors gone!
                  Look amazing!

                    That error looks fixed here too ! Goodbye padding problems, even on low resolutions !

                      Luoshuang alright well, seems like we're not out of trouble yet !

                      I've got this Assertion failed crash when trying to bake one of my scenes : could it be a problem with one of the assets in the scene or is it Prometheus's fault ? I've seen errors of this kind in the past with GPULM.

                        Luoshuang - could you release "official" version of GPU Lightmass for UE4.22 on the 1st page of this thread as usual ?
                        Thanks!

                          It looks like one of your mesh is generating zero triangles (maybe a kind of special mesh, or the mesh has problems)

                          Which "official" version are you referring to? You mean - a port of the 4.21 version to 4.22?

                            Yes. Something that works correctly with 4.22 as a GPU LM baker

                              Urgh this is very possible, CAD stuff can give birth to weird stuff sometimes... will check tomorrow.

                              +1 on that, a straight port would be nice for now !
