YES! You can take the stock and rather bland looking "break caps" and replace them with more detailed ones. The problem is that you only see them for a second or two, and if you want the detail to be clearly visible the decks might need to be out of scale.
The ultimate SFC3 break model:
1. Ship breaks up along hull lines where logical fractures would occur.
2. Several parths of the ship are made to explode away as if a secondary explosion occured.
3. TONS of pieces!
4. Tiny little figures of people flying away from the debris off into space...
5. Life pods! Someone has been doing this for quite some time in SFC2 I think.
6. Better break cap textures, showing people running, force fields failing, corridors, turbolifts, quarters ect.
All this can be done, but nobody has yet.
