Thank you for the comment. It took me a while to understand the function for more advanced cloud animations. About the tutorial part my scene was heavily based on Martins tutorial for cloud animation an the scene he kindly offered for me to mess around with. I never did a tutorial before but i could try to at least show how i made this scene and explane why i did certain things rather then others. Let me know if you or others are still interested in a tutorial.
Best regards,
