I did that just yesterday and indeed... it gives you lots of control and
speed. You have no collisions, but sometimes it's enough. For
destruction stuff however, I doubt it.
I used the same technique on this shot 2 years ago.

The length of the shot and the deadline didn't allow for RBD simulation.
I needed something quicker.
Olivier, you can always have a look at this tutorial.

You need emTopolizer and the workflow is a bit convoluted, but it's true
you can work faster this way. Maybe it's possible to use Simulate Bullet
RigidBody on the particles at the end and set the particles sizes to
match the poly chunks. That could work for real simple stuff.
Don't give up on Houdini. For destruction stuff, that's where the fun is.

I think it's simpler to not involve ICE if you just want rigid bodies
with momentum (just simulation I mean).
Recently though I used a setup which was non-simulated, cracking geo
with implosia and then using emtools of some variety (I think from a
mootzoid video) - creating a pointcloud from polygon islands,
manipulating the pointcloud, and then that drives another copy of the
original mesh, worked well! Lots of control.

You are killing me with answer like that, but yes, it seems deeply
bugged, some demo scene makes xsi crash. That's really a shame.
So far I've found a working solution : Pimping the "Mom Emit
Deform Control" and setting the Mass to 0 (passive RBD) when
inside an Geometry and back to 1 (active RBD) when outside seems
workable.
Wish I could play with some states, will try later.
I'll rely on ice magic. I gave up on Houdini, Maybe I'll look at
some more tutorials during hollydays...

Try another software package like Houdini for that, or be
prepared for maybe more pain than you'd expect.
Momentum is a bit p.i.t.a dir complex Thinges
Sorry couldn't resist ;)
Every second time you playback it works.
Sim is never the same you press the button, always cache it,
otherwise you'll never get the same result. The sim engine
itself is pretty cool if you use it in another package, but
the soft implementation is half baked and feels dirty. No
offense to the developers, if it's a softimage problem or what
else ...
