          How can I restore CPU lightmass if I want/need to?
          GPU lightmass is giving me black splotches on furniture in a simple studio light scene even if Lightmap UVs are 100% correct. Testing the same with CPU on another pc shows no issues.

            Oh I'm having the same trouble here, even after uninstalling and reinstalling launcher and engine.
            I've restored baselightmass.ini and checked all the files that could be affected but still didn't find any clue. Also did some run test on other PC and everything was clean.

                Epic recently hired Luoshuang. There's Lightmass developments being worked on.

                  Good news. İ hope Gpu lightmass support multibounce skylight and use RAM.

                    You can try what Luoshuang has made for 4.19 already, his "prototype" uses GPU VRAM and has multibounce for skylights.

                      Not vram. Ram so system memory. Shared memory.
                      I've tried but can't see multibounce support.. You talk about 4.19.1??? I use 4.19.2.

                        thanks for the feedback guys! I'll give another try on a future project. My current one only works with the lights in the same level, I tried everything, even replace the lights with the default settings, but nothing work as expected for some strange reason... and since this isn't a dealbreaker for this project, I can continue like this...

                        This plugin is suck a nice feature, the fast visualization of light baking is like a dream. So I can deal with these little inconveniences here and there...
                        Hi!! Actually it worked fine with 2 light scenarios...but now i have 3 light scenarios, and the third one is black...so it seems it doesnt work properly...and it probably just supports 2 light scenarios...maybe Luoshuang can give us some feedback :-) ??? Thanks

                          Should be the same, this was baked with 4.19.2 and GPU lightmass with the settings visible on the bottom right of the image.. And there is definetly bounces from the skylight (which is the only light source in the scene, and has an HDRI filled in).

                                Maybe multibounce skylight is work but only vram work is useless. Because I have bad pc 16gb ram but very good gpu 11gb vram.
