        Hi guys,
        I would like to share my works done with Luos Huang's GPULightmass.
        Big thanks to Lous Huang for giving us this amazing tool which speed up the workflow and delivre a incredible results.

          Some of my work using this GPU lightmass. I only modeled the house.

            Thanks, I think it would be beneficial overall (let's say GPU goes down and people still need to work on the project while waiting on the new GPU)

            Also an interesting thing is that according to my measurement GPULightmass is actually 25~50x faster than CPU regarding indirect lighting sampling. However there is a lot of work that is still done by CPU (namely Signed Distance Field shadowmap calculation). So one purpose of this overhaul is to move these to GPU too. If someone has been already experiencing this problem (very low GPU execution time compare to total baking time) maybe can consider sending the scene to me to investigate.
            So, does it mean that 50% performance drop in simple scenes using GPULightmass is still going to be a way faster than building lighting for the same simple scenes on CPU ?

              Does anyone know why i get this circle artifact in my point light when i switched to GPU light-mass? Didn't have this issue in CPU light-mass, i am using 4.20.

                      I have a problem, when using a static direct light movable objects don't cast a shadow after baking, Help please.

                        Static lights don't cast dynamic shadows. You need to use a stationary light.

                          thanks! I’m new in Unreal so I’m learning and I wasn’t aware of this

                              unfortunately this is how works point light with length with GPU Lightmass. Better use rect light.

                                hi guys,

                                i know this irrelevant with this topic but;

                                GPU baker amazing feature but we need proper Realtime GI solution. i have some experiment on unity and result awesome(prebaked realtime lightmaps with reflection probe support) .

                                but unity using clustering phase on CPU ( per object lightmap resolution max 150x150 ish). if we got this feature in unreal within processing GPU (and unlocked lightmap resolution size) this will be really amazing.
