Hello, it’s possible to change gravity scale on rigidbody? Now i have gravity but it seems to be very fast when falling, i have platform jumper game and with 2d object and 2d rigidbody with correct gravity scale it works nice, but with 3d object with rigidbody it seems to start falling very fast.
Thanks for help.
Change the mass of the rigidbody. Either through the inspector or via code…
Mass does not affect fall speed. It even says so in the page you are referencing.
To change the effect gravity has on everything globally will be through physics properties
Edit>Project Setting>Physics>Gravity
To change the effect gravity has on individual objects is relatively easy for 2D physics with gravity scale, but there is no such thing for 3D.
For 3D You would be better off disabling gravity for all the objects which require a different gravity effect, and applying force to simulate gravity on them.
thanks a lot for both of you 
i will try it
