the properties of the primitives inside the group, you'll need to open it and
selected the individual primitives inside it.
Rigid bodies don't bounce enough.
Increase the
Elasticity property on page 3911 of the object. Try also increasing
the Elasticity of the other object involved in the collisions, as the elasticity of
a collisions is a function of the elasticity property on page 3911 of the two objects
involved.
Objects stop moving unexpectedly in the middle of a simulation.
This can be caused by objects being deactivated. There are two ways objects
can be deactivated: through the
world on page 4087 deactivation or, if the object
belongs to a constrained system, through the
Constraint Solver on page 3945
deactivation parameters
In both cases, try modifying the deactivation parameters for a less-aggressive
deactivation, or disable deactivation in general.
An object doesn't move during the simulation.
Make sure that you've added the object to a
RBCollection on page 3922 and that
it has a
mass on page 3911 other than 0.0 (objects with mass 0.0 are fixed). If
you are using
Fracture on page 4010, make sure none of the pieces is fixed (has
mass 0.0).
A keyframed object doesn't move during the simulation.
Make sure that you enabled the unyielding on page 3911 property for that rigid
body.
My old scripts don't work.
reactor exposes parameters and functionality to MAXScript in a much more
consistent and complete way than previously. For the update, some reactor
MAXScript interfaces had to be renamed, but all functionality exposed in
previous versions is still available, and a lot more functionality has been
exposed. While this means that some reactor-specific scripts need to be
updated, it also means that a great deal more flexibility and power is now
achievable using MAXScript with reactor. For more information, see the
MAXScript Reference, available from the Help menu.
