    I have installed Prometheus for 4.22 and results of baked light look like a complete mess.
    What is Prometheus for ? How to use it properly ? Does it work only with RTX ?
    To see anything I had to reduce camera exposure (baked image was overexposed) but results are not what I was expected .
    (I use GTX1080 if it is important)

    If you could port GPULM to 4.22 it would be great. Thank you Luoshuang

      Used 4.21 version normally, but after one of the engine updates, it completely broke my light builds with GPULightmass. Looked through crashdumps, and found error line, which maybe someone can explain to me since I'm not a programmer at all :C
      This thing repeats every time now when I trying to build my level. Maybe I did something wrong myself because on simple maps builds are normal, but why it worked previously then.

        I've uploaded Prometheus 0.3.0 for 4.22.0 Release. GPULightmass 4.22.0 is coming later.

        Also I added multiple parameters for Prometheus in BaseLightmass.ini

          Luoshuang - release GPULM 4.22 ..please, please... Prometheus at its current development state is completely not usable for production. Please port that GPULM to the new UE version.
          PLEASE !

          BIG THANKS !

          EDIT:
          - YOU DID IT ! Thanks !

              Oops I missed the progress bar fixed now, just redownload to update

              EDIT: FireflyClampingThreshold of GPULightmass 4.22 has been loosened to allow more contrast from skylight and correct brightness for emissives - if you start to see fireflies from sky or emissive you may want to set it to lower values like 10.0 (in BaseLightmass.ini)

                I thought that you drop the progress bar for a reason

                  Luoshuang if I may suggest that I recommend to set default values like this:
                  [DevOptions.GPULightmass]
                  NumPrimaryGISamples=128
                  NumSecondaryGISamples=64
                  FireflyClampingThreshold=10

                  32/16 is drastically too low value for an ArchViz (for example) - the "drops/splotches" that are creating the shading are clearly visible in shadow areas.

                  Maybe you could do some dropdown menu + textfiled + RUN button in your progress bar that could work like this:
                  -> Start Baking in UE4 Editor
                  -> GPU Progress Bar appears
                  -> Waits 30sec for any user action - if no action it uses last used GI setup
                  -> When user do any action above the Progress bar then the timer stops ( for example: click on any place at the progress bar window )
                  -> { DorpDownMenu } User can select one from four modes:
                  [ LOW (32/16) ], [ HIGH (64/32) ] , [ ULTRA (128/64) ], [ Use BaseLigthmass.ini Setup ]
                  -> { IntegerValue:FireflyClampingThreshold }: 10 (for default value)
                  -> clicking on { RUN } button will continue the bake process with selected GI setup

                  What do you think about that ?

                  EDIT: probably you will have to store current GI setup in a dedicated config file ( for example: Engine\Config\LastGPUGIsetup.ini )

                    Next question:
                    Is it normal that the GPULM bakes the shadows for that kind of light hole like this?

                    For every room with windows that kind of black belt appears in the middle of the wall ( in most cases is more subtle that this )

                        maybe a stupid suggestion but is your texture streaming disabled?

                        Comment


                          Yes, texture streaming is disabled in every single of my projects
                          This looks like a radiosity hemisphere GI or sth low smoothing - donno how to describe it.

                            Okay then I am out of ideas ^^.

                            I tried the values you described earlier in your post and it does look a lot better!

                              Hi everyone,

                              We updated the Situx installer to make it compatible with the new version 4.22 of GPULightmass.
                              Situx , we just sent you a Pull Request on Github.
                              We tested it quickly and everything seems to be working for us.

                              A very big thank you to Samuel who made this update on his lunchtime!
