Gravity The acceleration, in world units, the objects in a scene have due to
gravity. It is an important value because it affects the overall feeling of scale
in a dynamics simulation.
reactor will generate a warning if you specify a non-standard Gravity value
compared to World Scale (see following); that is, if you set the value much
higher or lower than 9.8 m/s2, where m is World Scales representation of
one meter. The warnings are provided for guidance and can be safely ignored
if you are happy with the behavior of your animation. The default Gravity
value reflects "real-world" gravity: 9.8 m/s2 (386.22 inches/s2) on the Z axis.
For more information, see
Scale on page 3896.
World Scale The distance in 3ds Max world units, that represents one meter
in the reactor world, and hence determines the size of every object in your
simulation.
NOTE Changing the World Scale value can drastically alter simulated objects'
behavior. For more information, see
Scale on page 3896.
Col. Tolerance (Collision Tolerance) One of the tasks that reactor performs
at each simulation step is detection of whether any objects in the scene are
