Can I assign initial velocities to objects? How?
Yes. At the start of the simulation, reactor assigns to each object the velocity
it currently has in 3ds Max. In other words, if an object is moving during the
frame range A to B, and you start the reactor animation setting
Start Frame
on page 4085 in between A and B, the object will start with the velocity it had
in your animation.
WARNING Make sure the object has the desired velocity at the exact frame where
reactor starts the simulation (Start Frame). Since 3ds Max usually decelerates an
object when animating its movement using keys at time A and B, starting the
reactor animation at time B won't add any velocity to the reactor simulation. In
order to have initial velocity in the reactor animation, start at a frame between A
and B.
