Start Frame When creating a world to be simulated or previewed, reactor
needs to access the objects in 3ds Max at a fixed point in time. This parameter
defines this point in time (in 3ds Max frames). Initial shapes, positions and
velocities are taken from the actual shapes, positions and velocities of the
objects in the scene at this particular frame. When creating an animation,
keyframes are created starting from this frame to the End Frame time.
End Frame The last frame to simulate. When reactor creates an animation,
it generates keyframes from the Start Frame time to this frame.
Frames/Key The number of frames for every keyframe that reactor creates
(time step). For example, a value of 2 will create a keyframe every other frame.
Increasing this value forces reactor to take bigger time steps, potentially
reducing the accuracy of the simulation; you might need to then update the
Substeps/Key setting accordingly (see following).
