Thanks for the offer but your good.
I just wanted to crack on with the code so opted to grab a few free packs but the work its going to take I might as well just make them myself, I can use blender I just haven't in a while so, you know, rusty.
I got a so called game ready spaceship asset pack here, same deal, double verts, hidden faces, overlapped edges, and the poly count is through the roof, bevel mods and gerbilles should be baked not actual geometry!!, they are not game ready assets and will take a lot of work to make them so, re topo or bake to low poly .... might as well just make them!
But low and behold the holy grail of addons:
SpaceshipGenerator ... even better than a lotto win, thanks Mr Genie! lol
