Hi Martin,
I appreciate your help. Well, it’s obviously a problem with the parenting. I noticed that the lappets weren’t moved around when I only chose the bell.000 and moved that around. I managed to parent the lappets to the bell. I move the bell and the lappets follow the movement. My next step was to create that empty and I parented everything to that empty. I just followed the steps of the tutorial. Now I have jellyfish.000. But my problem still exists. If I move the empty box the lappets are not included and are not moved around. If I choose bell.000 inside the empty box and move it the lappets will follow.
I’d like to send my blend file but I need some help how to do it.
