Well, try and find Pack3D, I am using version 1 for all the files, except the jar, I am using 5Pack3D.jar which seems to have a clone option..though what it does, i'm not certain of yet
You may need a 3D modelling program too, 3Dmax, Maya, Wings etc
Problems are abound though, TMAPs are NOT exportable/re-importable using Pack3D at the moment...
There is good thread here:

Can't remember where I got Pack3D versions...
ah here it is.. diving ducks filefront page.. not sure if they contain all the necessary files though..
