Yeah. I just copy the "Color Info Override" and my paintballs ONLY - you can't copy anything else over really except that. Then if you do have textures, I just use the above method as that's what I was taught ages ago.
Once you've got it right in PW and tested it in game, then you go back the the LNZ and change "\art\textures\example.bmp 1" to "\Resource\Dogz\example.bmp 1". Doing it in PW just means that you get everything else definitely right.
Neco thanks for adding your info I was trying to figure out a way to explain it haha. Hmmm strange maybe Pollypup is onto something with the texture name. Griff idk why people have issues like that with PW? I've never had a problem with PW when paintballing etc. I use it a lot and send horses created on it to others with no issues. However they might have been modding on PW and yes if you muck around with the actual balls and don't save as you go there is a chance you'll "screw stuff up" Hope my randomness helps.
