after you downloaded the "Engine" folder you can go to C:\Program Files\Epic Games\UE_4.24 and replace the "Engine" folder. If you wanna change the Quality Settings, you can create a Lightmass.ini file in your Project "Config" folder.
now you can set or change these values:
FastPreview:
NumPrimaryGISamples=16
NumSecondaryGISamples=8
MediumQuality:
NumPrimaryGISamples=32
NumSecondaryGISamples=16
UltraHigh:
NumPrimaryGISamples=64
NumSecondaryGISamples=16
Extreme:
NumPrimaryGISamples=128
NumSecondaryGISamples=32

Thank you for this release! Works for me.
Could somebody clarify what is going on at the moment with GPU Lightmass?
Luoshuang is not working on this particular GPU Lightmass Lightmap renderer anymore himself?
But he is working on an official DXR GPU Lightmass Renderer that will be part of an official UE4 release in the future (4.26 maybe)?
Is this correct?

Thank you very much for this.
I can't access the Sources code, I get an 404 error every time I do have a basic account in github, there is something I am missing?
Thank you

It seems that dev-rendering is the only branch that currently has the upcoming DXR GPULightmass on it. You can follow its commits here (obviously includes a lot of non-GPULM stuff) https://github.com/EpicGames/UnrealE.../dev-rendering

* 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).
* Enable GPULightmass plugin and restart the editor currently no UI has been setup, so just a bunch of console commands r.GPULightmass.xxxx controls parameters and finally, ToggleLightmapPreview to start GPULightmass in editor.
* GPULightmass throttles itself when the level editor viewport is realtime. To make it run at full speed, uncheck 'realtime' in the viewport options.
P.S.:I tested this on my GTX 1070. Everything is working fine.

I got the GPULightMass for verision 4.24.1. However, I got a result with a lot of noise even I set the lighting quality to product level. Also, I increased some parameters in BaseLightmass.ini, and it was the same. So, need I change any other parameters? or It is the GPULightmass algorithm defect?
Thanks

I have installed gpu lightmass as instructed for version 4.24.2
My GPU only works at 4%-5%
How to make it work 100% using GPU lightmass ?
