I just ment to provide a reference. I posted that part after you posted your
reply, so couldn't possibly see it in advance.

> but I recall we had both stacks of boxes
(first level) and articulated bodies such as "mutant tail thing" which
is essentially a large multi-part mace. I guess even the doors and hoods
could be considered articulated, as they were hinged. The main problem
scenario for us was tall thin poles with rotation about perpendicular to
the long axis of the pole such that when one end of the pole was
resolved, it'd just push the other end in resulting in small jitter.

Yes, it does work, but it is more stable with smaller timestep. We initially
wanted to make our whole system run at frame time, and it worked even  for
stacks and for articulated systems. Mostly. But it jitters too much if
systems are a bit more complicated (like ragdolls), or if stacks include
articulated systems etc. So we now use substepping for all clusters with
more than one body.
