The object becomes a rigid body as soon as gravity is added to it. As I said, when I add the gravity the object does not fall into space as it should on my Mac. I tried this same process on a PC on campus (Create a polygon sphere, fields_gravity) and the object reacted the way it is meant to, it falls straight down. I was thinking that maybe there is an attribute that I need to adjust in the gravity node but I am not sure which one.
