not a simple task.
but stay away from dynamics in this case.
your best bet is to use clusters and somehow is to set driven key them on a "roll attribute.... adding a lattice might smooth the overall look of the "paper rolling" beware of order of the deformers though.
sory i cannot elaborate more on this. but this sounds pretty interesting. waiting to see how u resolve this. pls post when u do :headbang: :saywhat:
