hi @anonymous-edc , @AleksJN
Firstly you must use the correct posting in the Conference/thread
This post is regularly updated.
This uses the original update method from Luoshuang’s GPULightmass Unreal Engine 5.4.3
This overwrite the original 5.* Production Binary in both cases.
Luoshuang’s GPULightmass Unreal Engine 5.4.3 was the last update for the original baking method. Due to severe technical problems causing corruption of projects in later versions
In my case work stopped and as the Unreal Engine 6.* (UE5/UEFN) scheduled Q4 2027 wont be any updates as the only version is to build from source which is little interest to developers.
