BTW LIthunwrap 1.3 was released as Freeware, and this version remains freeware. It is true, the file is no longer hosted by the author, but you may find it elsewhere.
Yes, it's a good idea to buy UltimateUnwrap3D, the sequel of Lithunwrap, not only cause it's nice to support the author, but also because it's the only tool that is capable of exporting AND importing animated B3D Files. And of course convert them from/to other formats.
Lithunwrap supports many formats such as 3ds, obj etc. but no B3D and no animation. So the workflow with Lithunwrap 1.3 has to be strictly this way:
-model
-unwrap textures
-animate
while you can mix these steps when you have UU3D.
But still, Lithy is for free and when you really need a free toolset, it might be the best choice.
