Unlucky's made multiple Megalodons (you should see his newest one) and they're all gorgeous. Yet they're denied for minor problems that although a seasoned modeler can pick up, the vast majority of players here would never notice. I'll say that I did have to spend some time fixing hardpoints in one CMP I received, but after that, it was pretty much good to go. Minor texturing issues are negligible and generally, are only noticed if clearly pointed out. I suppose maybe the severity of this scales up with ship size, and I can see it being worse on smaller ships.
I don't even think these kinds of issues are anywhere near as bad as the countless ships that currently shoot through themselves because that's the best we can do with turret hardpoints in FL's limited engine.
To be honest, I think I'd rather have brand new models for the recently 'added' Core ships with slight textures issues, rather than them just being clones of the BHG line. IMO I think recycled content is worse.
Small texturing issues can just be fixed at a later date if it ever becomes important enough to warrant that.
