I personally find hard surface modeling with Subd's in mind really tough,
simply because you run into problems like the ones you are getting frequently
and easily. You need to jump through all kinds of hoops (additional edges and
bevels, creases, hard edges) to make certain mesh topologies look nice when
subdivided. What can really help is to break the mesh up into pieces whenever
you don't see the resulting open edges (e.g. for lids) or where sharp edges are
even required, e.g. when the object you are modeling realistically consists of
several glued or screwed together parts that form sharp edges where they meet.
Other than that, it is almost always more productive to model higher-res from
the start and not subdivide at all. At least this is what Vitaly Bulgarov
(http://www.bulgarov.com/index.html) seems to be doing judging by this
timelapse video of his (one day of work):
http://www.youtube.com/watch?v=4ct9voyU3h0
His edgy, mechanistic style does certainly work in favor of the "no SubDs"
paradigm, but I'm sure it can translate to other (more roundish) styles too.
Thanks guys!
Geo Approximation doesn't have too much effect at this moment, setting to Angle
dependent helps a bit. HQV also helps a bit but nothing really helps this. So
guys, so there any special tricks you use for daily hard surface modeling?
Cheers!

oh, and make sure to check shading with highquality viewport, which pixelshades
instead of vertex shades

Just a thought but have you looked at the geometry approximation settings?
Maybe there is a difference there?

looks like your surface has more of a curve to it though, the more curved it is
the more issues like that will show up..
also, i doubt 3dsmax subdivides much different from softimage or maya for that
matter, maybe you could ask the guy to send you that piece of the model as an
obj so you can try it out.

Thanks James,
I thought and used similar approach but yet, here we tried to reproduce a
similar surface that guy does, and we can't replicate the same smoothness
[cid:image001.jpg@01CE9F44.70B6E530]
As you see, the unsubdivided model has clearly visible shading issues, and the
subdivided has too. I made a similar (almost identical) topology around the
corners, and it drives us crazy...

what kind of shading issues are you having? and that guys model is nice, but
certainly not perfect. and entirely possible to do in softimage with standard
tools.
i model cars in softimage all the time with no hassles. just make sure you plan
out your mesh / loops early on. make all panel cuts etc after one or two
subdivisions down so you have the main surface already clean. also if your
going realtime, use shading edges or hard edges...there is nothing else :)
if you really want to do tricky cuts, sometimes what I do is dupe the mesh,
locally subdivide it a few times, then project a fairly dense curve onto it via
shrinkwrap.
delete the subdivided mesh, (freeze the curve beforehand!) then use the curve
as a snapguide for your cuts. im sure there are plenty of other ways, but this
is what works well for me :)
cheers,
james,

Hey folks. On CgSociety there is a talented guy modeling a MI-24 helicopter.
He's using Max for the modeling, and he's got some extremely powerful technique
to model lids, insets, etc, without ANY SHADING ARTIFACT.
I tried several things that I am aware of, but in vain, I always had shading
issue on my model, even on extreme subdivision.
