hi @Miguel1900,  
This is the run of my LGPU 5.4 binary 17th July on the newly updated test example.  
Using BaseLightmass.ini

> ;new values for HIGH discovered recently  
> ;Lighting Quality High Scalability high  
> NumPrimaryGISamples=64  
> NumSecondaryGISamples=32

I have focused to the back to show the shadows on the back wall which is new for LGPU 5.4 . My hope is that when I have put the LGPU patches into the latest version (ue5main) I get at least this good a picture.

The screen dump below needs to be downloaded to actually see the shadows properly as its so high res.
