Screenshots of your set-up and the problem would be helpful. How are you “picking up” items? Are you attaching them to a player character? Do you need to simulate physics on the items once they are picked up? If not you can simply disable physics on pick up. You can also set momentum, inertia, velocity, gravity etc on the objects to change how they are affected during player movement. I just don’t know enough about your set-up to really help you figure out how to do what you want to do.
