yep, that definitely helps! Basically, what I needed most was to know about the Obj2DatTex.py thing.
Not sure yet if it will work, but I already have access to pre-made models of the ship in Obj format, so assuming the texture files work right, it should simply be a matter of converting with Obj2DatTex.py, and creating the OXP file.
I'll definitely have a look at doing this sometime very soon! Thanks!
