I try to animate a futurist helmet like Matt LeBlanc’s one in Lost In Space.
So I modeled all the parts that will rotate on their axis (situated on the ears of the character).
I could animated by keyframes the unfoldment of the helmet, but I’d like to create an expression that does the job automaticaly.
For example at time 0 one part of the helmet is at its initial rotation angle, then at time 10 it begins to rotate, and finally at time 20 it reaches its maximum rotation angle.
My problem with expressions is that I can’t create a progressive rotation movement, I don’t know how to do it.
Thank you for your help, and please excuse my english
