If I had to guess, I think a sticking point with Epic putting this into the engine as an official plugin maybe due to it being a NV/CUDA only feature. Judging from their previous stuff, they prefer things to be hardware agnostic. I guess if it ever gets ported to OpenCL, maybe it'll be an option.

Dumb question, but how do I know if GPU Lightmass is working? The progress window popped up once in one project, but when I open other projects and bake lighting it doesn't open. Is there a way to tell if its working or not? Does it only work if X,Y,Z or is it working but I just cant tell?
Thanks,

Luoshuang so i came across this just yesterday, and i couldnt Keep waiting to test it myself i did a realy quick and dirty simple Scene just a room with a Sofa.
So far im so fkn HAPPY !!!! that i FINALY got rid of those fkn anoying ugly black splotchy lines in Corners no matter how perfect your UV maps are i think everyone here who played with extremely low Level scale Settings knows what im talking about. But i also noticed a few Things i might be wrong.
After the First Bake which took only 1:48 with 2k Lightmapps on every single object and 4k on the walls and Floors o.O i was first impressed how detailed the shadows are and crisp and clean everything looked i could never achieve that with the normal Lightmass even with high Settings.
BUT !!!! after i took a look at the Lightning only mode i noticed immediately that there is no Sky light Multi bounce ???? the whole lightning no matter how detailed and crisp and clean it looked. It was too dark also it lacked in Depth and all those nice collor variations you get from the sky light Multi bounce which i used the day you released it back then before Epic itself did it.
Question: Luoshuang do you plan to implement the sky light Multi bounce for future Builds of the GPU Lightmass ? i think if you could manage to implement it we could finaly achieve Ofline Rendering Quality in UE4 with reasonable Rendering Times
Lightmap resolutions used in the screenshots 2048 for the Sofa, Plant and Window and 4096 for the Walls Floor etc.
GPU: Gigabyte G1 Gaming GX 1080 OC @ 2,1GHZ
Render Time GPU: 1:48
Render Time CPU: 38:41
equal settings

This could be related to the GPU timing out due to heavy workload, it's usually accompanied with the 'unspecified launch failure' error. Did you change the TDR (Timeout Detection and Recovery) to a higher number in the Windows registry? Windows defaults it at only 2 seconds, try changing it to a higher number like 300. It's explained how to do this in the original thread post, or you can look up it up yourself on other sites.Last edited by Logithx; 05-18-2018, 06:19 PM.

For the skylight multibounce, since GPULightmass doesn't uses photon mapping the skylight gets natural support of multiple bounces.
Currently the workaround is to turn off two sided on these materials. While it should be a not so hard fix on my side, I'm scheduling my relocation so I cannot write codes in recent days. Sorry for that!Last edited by Luoshuang; 05-18-2018, 06:38 PM.

Hello,
we have installed the UE4.19.2 and the GPULightmass 4.19.2.
When we try to build a scene the GPU Renderer crashes with the message "Illegal Memory access was encountered"
Does anybody know how to fix this ?
We tried to add the TdrDelay in the Regedit but this doesnt work.
