Explosion / debris & emitter settings ?

Hi,

Has anyone done any cool explosions in Torque ?

I've been trying to learn the emitter/debris settings
for about a week now, it looks like you can add smoke
animations for advanced movment of smoke etc.

I'm also trying to figure out how to make an indentation
in the landscape when a grenade explodes.

I know I can use decals for the texture, but how do you make the hole
in the landscape after the explosion ?

if anyone has any advise on variable settings in the emitters etc.
I would be thankfull, it is taking weeks of tinkering to figurout
regular simple things.

I've made a tight greanade explosion with a nice concussion
radius but the particles move two slow, anyway I'm going to be animating swirling smoke next.

Has anyone done this in there game ?

I'ts been TONS Of work for everyone I know.

Also, I'm trying to make the explosion tight & fast but when I adjust
the velosity, it makes the explosion to big, and the other way it's two slow :(

R there any resource links ?

thanks so much,
