Hey Curt,
This is the process I use in Blender 2.49 - its slightly different but similar
for Blender 2.5x
Use face select mode, select the faces you need to flip, and in 'mesh tools'
click 'flip normals', then re-save your model - that *should* do the trick.
Another useful trick is to click 'show normals' - you'll then see a small blue
line extending from the centre of each face in the positive direction - if the
normals point inward then they need to be flipped. The normal size can be
changed if they are too hard to see.
Regards,
Chris Wilkinson, YBBN/BNE.

Subject: [Flightgear-devel] Blender question?
I have a hopefully quick question. I've generated a 3d model mesh in ac3d
format. I'm doing this from a perl script and I posted some pictures and
details of the actual model here:
http://www.flightgear.org/blogs/curt/uas/misc/3d-modelling-with-perl/
My script just generates the left half of the model. I assumed I could just
import this into blender, duplicate the half and mirror it and produce the
whole
model. I'm new to blender, but I managed to duplicate the side and mirror it
and the mesh looks perfect.
My problem is that when I export the full model, the mirrored half is black
from
the outside. When I look inside of it, it's shaded properly. It appears that
when I mirrored the surface, the face ordering didn't change so the mirrored
half is inside out. I've been trying every possible face/normal/edge option I
can find in blender and haven't been able to figure out how to get my faces
back
the right way. The original half of course looks just fine.
It's probably something super simple, but I've googled and haven't found the
right set of keywords I guess. Is there an easy way to get all my faces the
right way so both sides of my model are right side out and look correct?
Thanks,
Curt.
