Physics and building blocks

I have a game in which I construct a shape from cubes, and then move the shape around.

I have tried two methods of connecting the cubes:

  • Using parent/child relationships
  • Using Configurable Joints

Using either works well enough except during periods of high joint stress (fast rotations, falling, collisions) the cubes wiggle and wobble a great deal. The wobble is reduced with increased mass of the cubes, but that also reduces their maneuverability…

Could anyone recommend a method that would reduce the wobble?

I’d suggesting reading up on the options in the Physics Manager and playing with the various settings therein.
