    * GPULightmass throttles itself when the level editor viewport is realtime. To make it run at full speed, uncheck 'realtime' in the viewport options.
    Could you share some more info? Like;
    - your description sounds like its a realtime solution. Can you still bake it into lightmaps?
    - how is the quality compared to the native lightmass and Luoshuangs lightmass?
    - same for the speed?
    - anything else interesting / remarkable?

      * Download dev-rendering branch from GitHub and build it.

      * Enable ray tracing (including switching default RHI to DX12 and check 'ray tracing'. And having a DXR capable graphics card with Win10 version >= 1809).

      * Enable virtual texture and virtual texutured lightmaps in project settings (optional, yet without this realtime preview in editor will be unavailable).

      P.S.:I tested this on my GTX 1070. Everything is working fine.

              4.24.x works fine. The last available is 4.24.2.

                  hows memory management working with the new gpu lightmass compared to luong's one? is it solely relying on gpu memory (non shared)? (ask because I 've been having some "out of memory" issues with some scenes, using rtx2080 (non ti) and 64gb ram that dont get used much while using luong's gpu lightmass. What about speed of bake any comparison tests? Constantine's work looks great btw.
                  Curious to know more details..
                  cheers

                    No it doesn't. You only get direct light from it, no bounce light.

                      hey everyone. Do you know if UE 4.25 GPU baking will support Mulitple GPUs platforms? Is there any comparison between GPU and CPU light baking time efficiency?
                      Thanks for any answers.

                          Hi,

                          i get build error on devrendering branch. tried "425-plus" branch and build done with no errors and working fine but that feature (rtx gpulightmass) seems only on devrendering branch.

                          How did u build devrendering branch with no errors?

                            So I really like using GPU Lightmass. but I am not a programmer so when people said 'just download and compile for the new version', it is very hard for a none programmer to do that.
                            I was using GPU light mass for 4.24.1 when we had to update to Unreal 4.24.3, GPU lightmass didn't work anymore. so what changed??
                            I am thankful for the people who take their time to prep for each version, they are doing it for free!!

                            But really for people like me, we just had to sit and wait for the new updates, If I know GPU light mass would not work in the latest version of Unreal I would not upgrade, but we had a problem with Data Smith and it only worked with the latest version.

                            Can someone explain what to do to upgrade for each new version? where can I look at the source code of GPU lightmass and see if I can fix it my self??
                            All the Github links show missing to me, I have signed up but still, I don't have access to those links.
                            Thank you.

                              Same problem here.Multiple build errors on the Dev-rendering branch. Installed the 4.25.0.p1 and too bad - the plugin isn't in there or...?

                                Same thing happened to me as well, although a few weeks back the devrendering branch could be built without any problems. Hopefully, the problem will be sorted out soon
