I have been using the mirror option to create identical parts (wings, ailerons
etc) for an aircraft. The model looks fine in perspective view but on exportingbones,it to Fs2002 the polys are "inside out" - they are displaying the inside face
of the poly, not the outside.
I tried the flip normals option in GMax but it doesn't seem to do anything.
Is there another way? I would hate to have to redraw each item..
Try adding a normals modifier to the affected geometry, instead of just
flipping or unifying them through the modify palette. While the methods appear
very similar in function in Gmax, there is a difference. Trust me. You may
have to isolate polys and elements of entities and apply the normals modifier
on an individual basis to get this problem fixed, but it will work. I have
found that mirroring geometry doesn't always work very well with exporting to
an FS model. In general, I don't deal with this issue as I create model
geometry in my drafting/design software, then import it into Gmax using the 3ds
and dxf import maxscripts. That is not to say that I haven't had to deal with
this situation. If you haven't already, check my previous posting for info
regarding this issue and others. The materials info should help you identify
problem geometry before exporting. FS will only render one side of the polys
that make up your parts. This side is defined by the direction of the face
normal. Gmax, however, doesn't care about normals quite as much in certain
situations, and while parts may look ok in Gmax, they won't appear correctly in
the FS model. In Gmax, the normal issue can be "solved" by the application of
a 2-sided material. This is not a true fix, even though Gmax displays the part
correctly. As a base rule, don't create or use materials that are defined as
2-sided. As I mentioned before FS doesn't handle the issue in this manner and
can produce undesired results. I'm pretty sure this posting will sound a bit
cryptic and vague, and I apologize for that. To be honest, with what I learned
from using 3D Studio/3DS Max over the past 6 years, I know that I could help
answer most of the issues posted here regarding Gmax with a few tutorials and
sample models, but my current situation (really f@#king bad) precludes me from
doing so. I hope that you (bones, Dennis and other readers) can get at least a
little help from this. Currently I can only hope that it does help, and wish
for things on my end to look up a bit in the near future. I try to post
helpful information, but with all the other crap constipating my brain, I'm not
even sure if it ends up making sense in my postings. This is probably more
than any of you wanted to know, but I felt an explanation might be in order.
Just keep working at it and you will succeed. I will try to help when I can,
but I feel as if my tank is almost on empty and I'm running on
fumes...sometimes life can royally suck....
