I discovered I needed this effect one day so I pulled it out of Unreal tournament, and converted it over to Deus Ex.
It still works the same except for wallfragments and woodfragments are the same. You can still set each with different skins though.

Installation:
Put ExplodingWall.u into your deusex\system folder.
The new effect is located in classes->effects->explodingwall

Theres an excellent tutorial on how to use it:
