Hi @wawoo,
I am a contributor to
Luoshuang’s GPULightmass - LGPU 5.4
In the thread you will see we had major problems with lighting of shadows in 5.2. It was so bad we did not make a version for 5.2 and moved on to later versions.
I cannot guarentee this will fix the problem, but this independant developer version might work.
