Could you share some more info? Like;
Constantine ChesirePRO test it in here:
ArtStation - UE4.26: GPU Lightmass 1
Just want to confirm Ue4 rect light Global illumination is not supported by GPU Lightmass? I have made small test scene consist of rect light is not getting GI.
RectLight works fine with GPULM
@**Muchasty **ok thanks,where can i find GPU Lightmass 4.24.3?
4.24.x works fine. The last available is 4.24.2.
What is the GpULM max light ? still 4 ?
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.
where can i find GPU Lightmass 4.24.3
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 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
this is **'s GPULightmass **thread, can you open a new one for general GPU Lighmass discussion?
i dont see gpu lightmass plugin in 4.25 preview 1 
hi is there a easy way to inbstall the gpu lightmass im not a programer so i dont know nothing about coding i mean i cant find that easy bat installer that lets you choose the quality does anyone have that .bat installer for 4.24.2 ?? pleaseeeee
you can download the code here: https://www.dropbox.com/sh/iejfroyne…2Z90q7cfa?dl=0
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
