GPU Lightmass gone after porting to UE 5

Hi everyone,

I used GPU Lghtmass for my project in 4.27. After porting my project to 5.0, the GPU lightmass button is greyed out.

All ray tracing and virtual teture are still enabled, I haven’t change anything.

Has anyone encountered this problem as well ? Have you fied this ?

I thought opening the project with UE5 would copy the project but it has been updated instead. I no longer have the 4.27 version to work on…

Thank you for reading

It seems that UE5 release does not support gpu lightmass for gtx1080ti anymore. bummer…
