I've made a tutorial on how to convert .ltb files to .smd files. There's an imgur gallery, a video guide, and a quick text guide. You need 7-Zip and Blender (or any modeling program that supports .smd files).

Text Tutorial:
locate rez2 folder
open with rez explorer
extract certain folder/file you want
rename the extension .ltb to .lzma
open 7zip and extract .lzma
rename file back to .ltb
run as admin LTB to smd.exe
locate ltb (1st button)
ltb to lta (2nd)
lta/ltb to smd (3rd)
open blender
import from smd
make naughty stuff
