I'm assuming you're taliking about the glow groups for SFC3. There is an SFC3 Tool Kit available that allows you to adjust the glows - colour, inensity and locations... JOKER has also got a rather good tutorial on how to create break models using Max.
If you wish, I can forward you the toolkit. There are some rather cryptic instructions included, but if you're stuck drop me a PM and I'll help you as best I can.
If you do not have Max, please advise how many models you need broken. If the numbers are not prohibitive, I could possibly assist you in that regard also.
