Warzog... I've taken a detailed look at the carrier model, and this is what I think...
1. The way its Materials and textures are set up doesn't translate directly to CMP/MAT very well. I tried a quick go at it, only to find that most of the model wasn't assigned textures properly, and once they were assigned, I had endless issues with whatever tweaks were done to make this model work for export to the Freespace II engine.
2. The model has some serious structural problems- mesh edges that aren't aligned/welded properly, and other things. And it has lots of greebles that are... to be charitable... poorly designed. MS3D's model cleaner helped some, but to really fix the geometry so that it was truly airtight would require an hour or so working on it with Rhino's poly toolkit. And it's such a simplistic design... why bother?
In short... I've messed with this file for about an hour, and I'm already very unexcited by the prospect of messing with it further- I'd rather rebuild it from scratch than keep messing with a model I don't much care for that would never look all that great in a newer game engine.
It's just not very well designed, as a game model, imho, and the texturing techniques used were super-primitive... it just uses tiles for everything, even where it doesn't make any sense. And having the "core" exposed like it does means that people will inevitably try to fly through it... only to run into the SUR... it'd be smarter (and lower polycount) to just model/skin some doors...
At any rate, I'd rather rebuild it from scratch... I could make a much nicer model, with a higher polycount to be sure... but only where it'd make sense, and much nicer UVmapped texturing. But you're going to have to stand in line... I have about 15 models that've been sent to me for WOS, and they all need fixing and skinning for Beta 1
