    Hey guys, how do you get such smooth results from the gpulightmass? I always get noisy results. Are there some denoising options for the lightmaps?

      1.World Settings / Compress Lightmaps unchecked.
      2. BaseLightmass file - [DevOptions.GPULightmass]
      NumPrimaryGISamples=128
      NumSecondaryGISamples=64
      3. Good UV in geometry and high Lightmap resolution.

      That's it!

            Hi ppl!

            New in Unreal Engine here

            I have a Titan Z from 2014 (a good friend gave it to me a few months ago) and I'd like to know if I can use this with my graphic card or is not compatible with this plugin.

            Thanks!

                  Hey guys, Im really getting into all this stuff. Already tried out version 4.26 (developer) with built in devrendering plugin (by Loushuang who works at epic now). Its great but not very stable for larger scenes so far.

                  Still I got some questions for this original Loushuang 'plugin' I couldnt totally answer myself: Are all the lightmass settings (world settings) available when using this 'plugin'. Somewhere I read not all of them actually change something because of the changed baking process.

                  I lately got problems with splotchy indirect lighting. How often do you guys got problems with datasmith-generated lightmap UVs? Im still not sure if my problems are caused by my lighting settings or my lightmap UVs.

                  Im really thankful for all the information in this thread and hopeful version 4.26 to bring easier and better results for ArchViz.

                              Check if you don't have a skybox mesh or something like that with cast shadows on. Even with an unlit material, that'll block GPU lightmass indirect light. If you have one, set a lit material to it, deactivate Cast Shadows and set your sky material again.

                                If I understood this works only on Nvidia gpu-s? Since I wanted to try this on multiple Radeon RX570 cards is there a way to make that possible?
