resize particle emitter

I have a particle effect assigned to the player, and I can shrink the player.
So I need to adjust the particle effect.
I need to acces the ellipsiod x-y-z values, but the scripting reference does not seem to list them, can’t I modify this in a running game?

You could use an animation to change the ellipsoid parameters.

Just use the Animation Window to create a clip, changing the values needed, and playing it when the player shrinks. I haven’t tried but I guess you could also create this clip dynamically.
