I'd honestly have no way of knowing. I've had the primary LOD around for a while actually, but fear of the pain and futility of turreting it in Truespace - and then putting in correct POF data on a model that will slow Modview to a crawl - kept me from doing anything with it until recently. If memory serves the primary hull went quickly, maybe as little as 45 minutes to model, an hour to texture. Maybe longer, but I honestly can't remember. However, now that I've got a working converter, it took me about 2 hours to LOD it, turret it, and give it all the necessary helpers and final POF tweaks that it needed, with having to do about all of that twice thanks to Max crashing on me about a dozen times. Again, it needs proper mass and MOI, but that's got to come from tinkering first and foremost, which I haven't had time to do yet.
