Let's say you want to add Bezrog the Ogre to your anim2 file, H slot 80. You import the .vd file, and save your anim. And if you are saving in another directory than your game's install, you have to move the new anim2 files into your game's install folder, overwriting the existing ones.
In bodyconv.def, you add the following line:
1681 80 -1 -1 -1 -1 #Bezrog the Ogre
This is assuming you have the recent version of the official game, which has its last bodyvalue as 1680. You can also start higher if you want to be sure. This line defines which anim file you are using. The first is anim2, then anim3, anim4 etc. Where it says 80, is the slot you see in Fiddler. Anything written after the # sign is being ignored by the game, but for your own sake, I would note either a name or description there, so you can keep track of the stuff you add. Especially if you end up adding a lot of stuff.
In mobtypes.txt you add the following line:
1681 MONSTER 0 #Bezrog the Ogre
Again, after the # sign the game ignores it. I am not sure what the 0 does though.
After saving the files, if you open Fiddler again, and look in anim2 slot 80, it should now say 80 (1681) there. If it does, and the animation is there, you are good to go. You can then just spawn a creature and do [set bodyvalue 1681 on it. If it changes to your new animation, you have done everything right. If not, you are missing something.
I hope this works, and if you have other questions you are welcome to send me a PM.
