Problems with .luv file

I have a problem when importing the .luv file from lith unwrap.


I edited all the model bits I want, tested ingame and everything is fine until I UV map in lith unwrap.

I set out my UV maps how I want it, then export the file as .luv.

I then open up my model in milkshape, import the .luv file and everything looks fine in milkshape.

I convert the ms3d file into .mesh, load up the game, but the model is now invisible.

The .luv file must be corrupting the model somehow, or i'm not doing something correctly. Like I said the model is working perfectly before I import the .luv file, so I know all comments and bone assignments are correct.

Any ideas/solutions?
