It seems there are a lot of blender heads out there wondering how to using lithunwrap in blender.
Here is a quick guide.
First of all you need to get your hands on lithunwrap (a windows prog). I found it here:
Then you need the blender obj IO script. It is available here:
Do your modelling, then export the object to a .obj file using the above OBJIO script.
Then load it into lithunwrap.
For the mean time, here is a short tutorial on using lithunwrap (not written by myself)
One thing I have noted though is if you do a 3d preview in Lithunwrap, it triangulates the model. Not handy if you want to import the object back into blender.
Hopefully this should get you guys started!
I am planning on writing a tutorial specifically for blender using lithunwrap. But this will do mean time!
