hi @AmrSrour ,
The FREE version of 5.4 (July 2023 is the only legitimate version that can be used FREE by everyone.
The licencing of 5.4 overlaps the code between 5.4.0 and 5.4.2 users could be unknowingly be using licensed versions parts of code.
Anyway, the 5.6 code is near completion with just the Nanite Landscape to integrate into the LGPU code. Many developers are waiting until 5.6, as this will solve problems with the integration of the newly released products for Unreal Engine.
With luck LGPU 5.6 binary patch will be available at the end of 2025
There WILL NOT be any further patches to 5.7 onwards for the reasons explained in
Luoshuang’s GPULightmass -announcement post 2500
Please up Epic GPU Lightmass for 5.7 onwards
