I am not sure about this as it never has happened to me. Do you have the object points place in the break. If your break has 3 pieces each piece should have an object point. I always name the pieces as well. If the model is akira the 1st piece is akira_brk_1 and then akira_brk_2 and then akira_brk_3.
For the object points I just import a stock model and if it has 6 objects but I only need 3 I delete 4,5 and 6.
The objext points get moved to where the pieces meet. Look at a stock brk for an example. Break models are explained quite well in the SFC3 model tools manual. That is a must read. Gives tips for the entire model process, including damage maps and light maps, damage points etc;;;; Hope this helps some.
(I hope this is for SFC3.)
Adam, Guest is wright about the names. You must name them as shipname_brk_# before exporting.
Even if you don't use the pivot point (I don't, it is too much work for a 3 seconds view of the ship) it should work fine.
The only problem about not using pivot points is that the the exporter changes the sequence number in the _brk chunks. (i.e. if you named the ship hull as _brk_1 and then the wings as _brk_2 and _brk_3, the exporter MIGHT change the numbers) I don't know why it does this yet but it's fixed if you use the pivots.....
Ah, and I always make at least 6 chunks since I don't know if there is a minimum.
Hope this helps.
