Thanks for your answer! Yes I have to be honest, if you use only few light sources or one simple skylight the Lumen quality is close to baked ligthing, but in a archviz enviroment with many different lights I can’t get the realism I’d like.
Do you have any advice on how to improve the Ambient occlusion effect on the heatsink in my pic? (left is baked, right is Lumen)
