I have a paper folded to make two flaps A and B.
If I rotate the flap A a little more, then It will just pass through the flap B.
I want to make the paper more realistic so that it pushes the flap B instead of passing through the flap B. If the pushing is too hard, then at least I want to prevent the flap A to pass through the flap B.
In other words, I want to make the flap A to be the active rigid body and the flap B the inactive rigid body if they are two different objects.
But this has to be worked within the same object. So this is totally different from the interaction of two objects.
I would appreciate very much if anyone direct me how to solve this issue. Thanks.
