Thank you very much for your response.
This seems like a huge possibility to implement it in my scene.
I am quite the nooby so I have still a few questions 
How did you define the âshutter numberâ in you graph and how can you control it in the details panel?
The scale of my slats are already in a defined measurement, so I donât have to change it I think.
Most important question:
The movement of my shutter is a bit different than in your video. It is like this(cannot upload video yet, so its a wetransfer link, sorry ):
Is it also possible to implement this movement with your approach?
Thank you again for your help.
