i recently took the rear half of my fuselage, put a spherical camera
inside and took a 2:1 pic of it after texturing each triangle by hand
into logical square-like groups.  then, i fixed the colors so they were
solid and not shaded and then used the image as a material map, mapped
spherically with the center in the same place as the camera was.  it
worked pretty good except for the lines i had drawn between each section
came out really bad.  the image size i had used was 2000 by 1000 and
while you couldn't see the jaggy edges of the squares, the lines in
between the squares were really jaggy.  i could increase the rendered
2:1 pic's resolution, but then i figured this trick couldn't be done
with the front of the fuselage due to my cockpit.

i think what i will do is either build-in the cutouts i need, or split
my model into parts as you suggest, but close each off so each can be
solid.  i know you don't know hamapatch gilles, but if any other readers
out there do, is 4 the largest subdivision you can get for an export? 
spatch gives up to 96, but can't export obj.  also, regarding 3dwin,
what do smooth angle and edge angle mean?  i'm getting pinched areas
where patches (now triangles in the conversion) meet.  i assume size
value is the scale.  hey gilles, you mentioned the new version of 3dwin,
doesn't it cost money now?  or could the free version be enough for what
i need?

thanks for your help.  sometimes i wish i didn't tackle the xwing as my
first project because the more i learn, the more i want to change it.  i
just can't leave it alone.  but if my current efforts work, i'll have a
version 2 sooner than i thought.  and r2d2 needs some minor changes
since i found better pictures shortly after i finished him.  oh well.
