Weather system UE5

Hello,

Currently I am working on a Archviz project were I want to show a buildingtransformation from old to new including a industrial place around it. For the building animation It seems like the best aproach to use UE5EA because of the dynamic shadows. However I would like to go from rainy to sunny as well to create a change in mood but there is no rain or weather system yet in UE5. I ordered a plugin which seems not to work in UE5. What would be the right approach? First build the scene in UE4 and then later do the animationpart in UE5? It would be great if someone can help me in the right direction.

ps: Changing some meshes by hand to use Lumen results in a crash :frowning:
