Hi
Thanks for getting back to this. In the meantime I found out about the problem: the addressable system doesn’t take into account shader variants that may occur when loading it into a scene that contains fog. In my case I had to set these values and now all works. But I think more people will experience this problem at some point so it probably needs some explanation.
Unity 2019.4.17
Addressables 1.16.16
URP 7.5.2
