Well in this new way u need 2 people.It's very simple 1.You cannot be host to do this. 2.Hold an object in the air. 3.Have your friend star a new round. You will notice the item will not fall when u start a new round.I hope this helps you in forging. I only tried this on Foundry so try foundry before anything else. I hope this helped.
Thats not necesarily floating objects, as the objects dosn't remain or float in the air. The object just falls. This is good for falling objects, but I'm not sure if this would be useful for making floating platforms.
