Re: Momentum setup ?
I agree with what most people have said here, it's just not worth the hussle to go at it with MOM, but if you insist rollback softimage to the exact version MOM3 was released for. At least your demo files should work. Like many I used MOM3, but found it unreliable at least with newer versions of soft. However it will be a very lonely place, the MOM exocortex list is pretty much dead, and you may find some big hurdles ahead. Why not give Houdini a shot? it seems like a perfect proyect to get started, and you can get a lot of help from odforce and sidefx..

Re: Momentum setup ?
I dont know, unless things seriously broke, I've done some pretty elaborate simulations (with large chunks and *tons* of tiny peices) using just the first momentum + IFX combo, and since then in subsequent MOM versions if anything suposedly got considerably faster (was already *fast*) and more directable. (and quite probably still way faster/easier than Houdini point simulations) But if you want your peices to then be say washed away by fluid particles, then Houdini would probably be best, Houdini for FX you cant go wrong, and it's community hasn't been and is unlikely to be displaced.

Re: Momentum setup ?
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.
