Yeeeessss its true!!! Believe it or not, this is Maya!!!! After days of trials, finally it works! And as sending cameras from Maya to C4d is hard as e hell, maybe I'll stick to this solution on the animated camera/character scenes, so my life will probably be easier. Ok, achieving this moving shape was not the most simple thing in the world, but as my history is still all there, I can tweak the CVs and still have the animation!!! so I'll just have to remodel the curves and maybe create a couple more deformers to stick the beginning to the mush flute.
