There is a visible gap between rigid bodies in the simulation.
Try reducing the
Collision Tolerance on page 4088 of the simulation.
reactor complains about a no longer existing node.
This can happen if you rename an object that is used as geometry or display
proxy on page 3914 for a rigid body; proxies are stored by name, so if you change
the name of the proxy you'll have to manually update the rigid bodies that
use it.
Error :All vertices are coplanar, use concave mesh.
By default, geometries in reactor are simulated by using their convex hull.
reactor can't create a convex hull from geometry in which all the vertices lie
in the same plane, such as a standard 3ds Max plane. Those geometries need
to be simulated as concave. Check the
Rigid Body Properties on page 3911 section
for more information.
Rope simulation modifies the smoothness of the spline.
Although reactor simulates cloth as a series of linked vertices, the
Rope modifier
on page 4049 tries to produce a smooth curve going through the vertices. In
most cases the curve generated by the modifier is suitable, but in some cases
(for example, if the vertices in the spline are far apart) you might find that
the generated curve is not optimal. In those cases you can:
■ Modify (refine) the spline below the Rope modifier so there is a uniform
distance, not too great, between vertices. You will need to re-create the
animation in order to see the final results.
■ Modify the spline after the Rope modifier using an
Edit Spline modifier
on page 1447. This is the most flexible option.
Animation works in the preview, but not in 3ds Max after creating the
animation.
reactor creates the animation for
rigid bodies on page 3909 by sending transforms
(new rotation and new position) to the controllers assigned to those bodies.
Some controllers, like procedural controllers (Noise) and some system
controllers (Biped) do not handle these explicit transform updates. To overcome
this, assign a regular keyframable controller such as Euler XYZ or Bezier to the
