    Do you have details on your hardware specs? I mean it could take hours and days if you have a really under powered video card. Or if you're using a laptop, it's throttling the GPU due to heat.
    So I have GTX 1080 TI 8gb, Core I7 4930k, 64 gigs of ram

    I removed all the additionally geometry I added and it's still taking about 10-20 times longer than it did before. I experience this before and remaking project / reimporting all the datasmith items fixed it. That doesn't seem like a practical solution though to remake the project every so often.

      Oh ok :/
      I was hoping, now that its source code is available, that someone managed to port it to 4.23 preview :/
      4.22.3 is buggy for me when baking lightmaps (see https://forums.unrealengine.com/unre...t-node-in-4-22 ), and it seems fixed in 4.23 so I was hoping to try this gpulightmass script on this version...
      Thanks for your answer

        Hi guys! I used GPU lightmass with Unreal Engine 4.20 and it worked perfectly with my GTX 1060. Now i bought the RTX 2060, but the GPU lightmass doesn't function anymore! I need to update Unreal Engine to a new version to use the GPU lightmass with my new grafich card?

          You need to double check your lightmap UV's, if there are overlaps, it will cause much much longer render time. Have you tried to reduce all your lightmaps to something very low? Like 64pixels and test the speed?
          Also be sure the UV channels are correct. Not much else I could suggest, your video card is really good for it.

            I assume you reinstalled your nvidia drivers. If you haven't, when you reinstall, remove old settings. I had a 1080 and upgraded to 2080 on 4.20.0, remove your Swarm cache as well. You do not need to upgrade your engine unless you want real time ray tracing.

              I have only installed the new driver for the 2060 by the GeForce Experience. How can I remove the old settings and the swarm cache?

                To do a clean driver uninstall I use the freeware Display Driver Uninstaller (DDU): https://www.wagnardsoft.com/forums/v...php?f=5&t=2213 . Run it with admin rights, then choose "gpu" and "nvidia" from the drop down menu on the right, then "clean and reboot" on the left. Once you have rebooted, install the new nvidia drivers.
                The program asks you to use it in safe mode, but I just ignore that (and never had any issue).

                    I installed and used the GPU Lightmass with Unreal 4.22 and for now it work fine, but... Someone knows how to change the GPU lightmass settings? In the 4.20 there were different Engine folder to replace (Egine Preview, Engine Medium, Engine High, Engine Extreme), but in the 4.22 they aren't and I don't understand how to set the quality for the GPU lightmass

                              Hi,
                              I'm working with the Unified 4.22 version, as I see there are no different settings such as Medium Quality, Extreme... Does this mean the Unified version has only 1 rendering setting? What if I want to achieve better rendering quality? is there any way to achieve this? Thank you.

                                ... I haven't been able to find unofficial references to RTX Lightmass. Can you please point me to what you are referring to?
