Clipping or Truespace Question revisited
Okay, I got my Hammerhead de-clipped but for one issue: the recessed jet intakes seem to be causing clipping becuase polys are parallel to polys in the hull:



This pic has a hull poly removed to allow better viewing:



Now, is there actually anything I can do about this or am I doomed to suffer clipping if I use these intakes?

Not really, it will clip to some extent no matter how you handle it. You may try angeling the intakes in a little so that the faces are not so parallel, but you aren't going to avoid the clipping totally.

Curses! Drat, and double drat! Bum clouds! Etc.

Hmm... oh well, perhaps I can un-recess the intakes... cheers Strat mate

Try making the back face smaller by .01 of a metre. You'll never notice it in game but the faces won't be parallel any more. Might fix the problem.
Karajorma's Freespace FAQ. It's almost like asking me yourself.

there's nothing you can do to avoid the clipping, but you can try to reduce it
and it affect not only the intakes with parallel faces, it happen anytime there are convex areas, since it depend by 2 (or more) close faces one behind the other.
So the problem is the distance of the internal and external faces.
Things you can do:
If you can, scale a little up all the mesh: the distance between internal and external faces will increase and the clipping will probably be reduced (but to gain major advantages you should scale it A LOT).
Another thing you can do is to make the intake more narrow, increasing again the distance between internal and external faces.
Making the intake deeper or shorter will not change the amount of clipping(how weird it is), but will reduce or increase the clipping area.
Last possibilty: change the intake shape, making the internal and external faces not parallel, with the inside of the intake very little, welding the borders: the clipping area will be reduced to just around the borders.

Well I fixed the intakes by having the back face only a few cm inside the edges... no so pretty but it doesn't clip :)

Now there's only one more issue with the fighter:





As far as I can see the lower vertical surface is trying to show through the wing (the clipping only displays from above the fighter). There are no interseting faces or other pieces of weirdness that I can see. Is this a similar issue to the intake problem?

exactly, the problem is the vertical face and the faces of the wing, one behind the other and too close.
it shouldn't be too hard to be fixed, for example you can just change the angle between the wing and the engine, by moving the connection edge to a lower position (the wing profile will be bigger), but other solutions are possible too
