You didn't state the duration of the fire in your script. Try SUMN.pms effectfiredamage 100, so it will burn for 100 seconds, or change it to however long the summon lasts.
Actually, once a shader is applied using the
pms command, it will remain until removed by the
sms command. At least, that has been my experience.
THE VYPER. YOU DID IT THE ATRONACH THING WORKED!!!
Glad you got it working!
Now do you know how I change the fire to a blue color?
That would require recoloring at least 16 textures and might change all of the flames in the game. Try replacing SUMN.AddSpell AbAtronachFireEffect with SUMN.AddSpell AbAtronachFrostEffect. That will add the frost effect of the Frost Atronachs. It would look like http://img410.imageshack.us/img410/3807/skeletonfrostlord.jpg
Also do you know how I can add the ghost effect?
Try using SUMN.AddApell AbGhostNPC and see if that works.
