Explosionquestion (Script)

[Optimus Prime]

atm i have this line

explode base type BITMAPONLY | BITMAP4;

and it looks not good when the unit explodes. The model polygons fly around but there is no fire or smoke after the parts. I want to give it more fire and smoke but the polygons shall still fly around.
Normally you can do things like that

explode rnanospray type FALL | SMOKE | FIRE | EXPLODE_ON_HIT | BITMAP4;

but that means that the part as one flys around and not the polygons of the one part. How can i let the part explodes in its polygons with fire and smoke after every part?
Is it possible?

thanks for every help!

SHATTER | FALL | SMOKE | FIRE | EXPLODE_ON_HIT | BITMAP4; ?

At least in OTA, it was SHATTER that made a piece explode into its polygons. Also in OTA, SHATTER + SMOKE or FIRE was a good way to quickly crash the engine on models with lots of polygons...
