I've been using a vampire ashes mod since it came out;

http://planetelderscrolls.gamespy.com/View.php?view=oblivionmods.detail&id=1921

and the script looks pretty simple;

ScriptName VampireDeathScript

Begin ScriptEffectFinish

if ( GetSelf != player )
pms testfireshader
pms effectAtronachFlame 5
endif

End

What I don't know is what triggers the script or how to change from atronach flame to something bigger like a Kvatch fire and smoke effect.

What I would like to do;

1. Kill vampire.

2. Vampire self cremates with FlameNode9 FireOpenLargeSmoke.

3. Effect stops after 20 seconds leaving charred corpse.

4 Preferably instead of the way he did it with a black textured corpse have a blackened skeleton as a container object when the fire stops.

The original does that with a 5 second timer and very small flame with no smoke, what I'd like is a more dramatic effect. I found a similar mod called ashes to ashes but that requires OBSE, what I need to know is how to do this without OBSE.

Construction set wiki is useless, all the tutorials I've found so far by googling this link to blank CS wiki pages or 404 errors, so if you're going to post links here please check that the links you're posting are not dead links.
