Yes that is possible!

First find the fx that you like and save the file names. (It's best to use a single fx effect)
Second, add this fx in your modbuilder!

fx,YourFxLocation

The root starts at: C:Program Files (x86)\Steam\steamapps\common\Call of Duty World at War\raw\fx
Then add this into your mapname.gsc.
Example:

Give it a name and your location.

level._effect["Your Effect Name Here"] = loadfx("LOCATION");

Still your root starts at: C:Program Files (x86)\Steam\steamapps\common\Call of Duty World at War\raw\fx
Then at last add this:

PlayFxOnTag( level._effect["Your Effect Name Here"], self, "JointName" );

If you want to place it on another joint choose something from this list:

Compile plus build your mod and you are done!
