I use
Physics.gravity =Quaternion.Euler(0, 0, -90) * Physics.gravity;
to rotate my gravities of 90 degrees. On my scene i have a cube in a closed area in a 2.5d setting (X,Y rotation and Z position frozen).
When i rotate the gravity the cube does not move, but if i check/uncheck Use Gravity in the rigidebody of my cube, he fall.
Is there a way to "restart" or "refresh" the gravity to really apply the gravity change.
