Have you tried using PFUSMOKE_MISSLE ? ( note spelling different from man page
) you will probably get puffs but you should be able to make then into a trail.
The source for pfuSmoke is in /usr/src/Performer/src/lib/libpfutil - if you
can't get the effect you want then use this as a pointer to writing your own
'long polygon with smoke texture on'. smoke.c does have some comments on smoke
dynamics in. I have asked internally to see if we have any example code for
PFUSMOKE_MISSLE but if anyone 'out there' has some it would help you.

Cheers
Rob
