      Does SP3 gave some kind of terminal velocity?

      I reject your reality and substitute my own.

        I dont think so. but alot of things seem to get so quick they go through other objects untouched

          I believe it does; when you drop an object, left to its own devices it will not accelerate to infinity. Objects that have, at some point, been propelled, do not really count...

            Ive always bin taught teminal velocity is caused by some sort of resistance. SP doesn't have any resistance

              Oh, but it does. Set gravity to 0 and push something. Does it continue for ever?

                True, it has some resistance, but not realistic resistance (if it was realistic, then falling objects would change position because of their shape; this doesn't happen). Terminal velocity is when the air resistance is equal to the force of gravity, so the object can't fall any faster. SP doesn't use proper air resistance, but it does have some kind of resistance none-the-less.

                  Well, resistance is easy; you just slow an object down by a set amount every frame. What you're talking about is air simulation as a fluid material, which is... hard.

                  Out of interest, where's Chris? He hasn't been on the forums for a while

                    There isn't a terminal velocity. The longer something falls the faster it will go.

                    There is a tiny bit of resistance that keeps a object from moving forever in zero gee. I think it can be reduced to almost 0 but if it is too low the models apparently tend to be unstable.
