Dear all, I am trying to create animation with gravity directional change, for example, gravity start from (- minus value) on Y axis, then it will change to (+value ) on Y axis again, so object fall down, but after certain time, change the direction of gravity and object start to come up again. I try to do with ncloth and bullet solver but both of the physics is only one way gravity. Once it set the gravity direction, it can't change the gravity direction. Either it goes up or down. I want to simulate with physics so it is important for me to be able to change and key frame parameter of the gravity values......
Anyone knows if it is possible to change parameter of the gravity during the time line?
I would sincerely apppreciate your help in advance.
Eiji
