    I'm fighting against Gpu lightmass using HDRI. I always gets fireflies and not so sure how to avoid it. Lowering FireflyClampingThreshold making lighning gets awful

    Any idea? thanks!

      I don't know who you are. I don't know what you want... but what I do have are a very particular set of skills. Skills I have acquired over a very long career. I will look for you, I will find you... and I will love you.

      Seriously tho, thank you for the incredibly quick response!

        Hello,

        This issue was introduced in 4.25 (since preview) and it's still there in final release, and is also there when baking with this GPULightmass. Luoshuang

          Try bumping VisibilityNormalOffsetSampleRadiusScale in BaseLightmass.ini from .1 to .5 (that's what I was told, I haven't tried it since I am still on 4.24)

            Helped but the issue is still slightly there.

            Edit: With 0.5 It's good enough in Lit mode now. I guess a bit of the issue has always been there I just wasn't looking close enough.

            Thanks a lot.

              Could you please post comparison screenshot (like you did before) with 0.1 and 0.5 values ?

                Please go dozen posts back. There is my explanation how to avoid splotches ( white[ light/baked reflections ] or black [shadows/openwork elements] ).

                      If objest is movable, GPU lightmass shouldn't have any effect on it, as it's not going to bake any lighting, right?

                        I just updated to full 4.25 release and replaced the engine folder with the download for gpu lightmass 4.25.0....however, when I start a build, it just runs default swarm agent and photon mapping. Any ideas what might be wrong?

                        EDIT: Nevermind, for some reason it just started working magically

                          Can somebody confirm: GPU Lightmass does NOT support Rectangular Lights?

                            You can use a "Lightmass Character Indirect Detail Volume" to get more indirect lighting samples that should improve lighting on moveable meshes.
