Hi @SalvaCGI
I have upgraded LGPU to 5.3 preview at
Luoshuang’s GPULightmass - Development / Rendering - Epic Developer Community Forums (unrealengine.com)
It was originally for Nvidia GTX series, but also works up to RTX 4400
The new GPU 5.3 binary new DXR GPULightmass.
Epic’s GPUlightmass - Development / Rendering - Epic Developer Community Forums (unrealengine.com)
is the built-in GPU version
