Do you mean the Simcloth part of MegaPOV? I've wondered about using that,
after importing the unclothed models into POV. Something like draping a
cloth over someone doesn't sound hard, though I've never tried using a Poser
model. But it sure doesn't seem like it would be easy to get "sleeves" and
"pantlegs" to work well, especially after the figure is posed.
However, if creating my own Poser clothes is pretty much out of the
question, I'm going to have to look at all alternatives.

Do you have some examples somewhere? I'd like to see how they turned out,
if you don't mind. Or if you're like me, it's 99% experimentation with 1%
results.
BTW(completely off-topic), I visted your website, and one of the links was
to a person named "John Uhri". I loosely worked with him on a project about
8 or 9 years ago for Auto Glass Specialists in Madison, WI. He was really
into mountain biking at the time. The project we were working on was doomed
from the start, I'm sad to say, but I still have fond memories of flying out
to Madison. I hope I left a relatively good impression for John, but I
wouldn't be surprised if I didn't. Unfortunately, I was working on a doomed
project in a language I didn't fully understand (VB), and it probably
showed. But now-a-days, it's good for a laugh.

MegaPOV 1.0 comes with a sample scene demonstrating a simple t-shirt.
Not on a human figure but on some kind of clamp but it should be enough
for a demonstration. Getting the sleeves stay around the arms when
starting the simulation is indeed not always easy but the code i used is
also extremely simple.

My bad. Next time, I'll post a link to files on my web-site.

Thanks for posting this here, even if it wasn't supposed to be here. Where
was it supposed to be? p.b.m?.
I finally got a chance to really look at it this weekend. While the clothes
were somewhat simple, it gave me a really good starting point, so I played
around with them, modifying things quite a bit in hamapatch, and referring
to this tutorial occasionally
(http://www.poserfashion.net/judy's_period_dress.htm). It took me awhile to
realize that when you IMPORT the OBJ, or DXF into Poser, you need to "weld"
the polygons. If you don't, your creation explodes into a thousand pieces
as soon as you run the cloth simulation.
Currently, I'm trying to make a simple dress for Penny, similar to what the
girls are wearing here http://www.beantoad.com/images/moss7.jpg in the front
row. It looks like a good starting point. While it's not exactly a simple
process, it appears to be quite possible. Right now, what I have created
looks a lot like a girl's night-gown. I'll post some pictures if I ever get
it into a decent state.
One problem: I can't get a decent model of Penny to import into Hamapatch.
I had to export to OBJ (from Poser), then import into a 3rd party utility
(IOB something?) then export as MDL, then import the MDL into hamapatch.
Unfortunately, by that point, Penny was mostly only a torso, with a few
triangles floating around for her head, arms, legs, hands, etc. Even so, it
gave me something to work with, and was usable to some degree.
From hamapatch, I had to export as a DXF file, which loaded into Poser ok
(the OBJ would not), although sometimes I have to flip normals, and
sometimes I don't. I don't know what causes that. Other times, I end up
with missing poly's in the clothes. Other times, I go to do the cloth
simulation, and I get stuck in an apparently infinite loop while it is
"Creating dynamics". Unfortunately, exporting and importing non-native
formats from different programs probably isn't an ideal situation.

For what it's worth, I find that UVMapper Pro does an excellent job when I
have to fix problems on obj files. It can remove or correct erroneous
polygons, let you play with the normals etc. I know it's a commercial
product, but it's really handy (even though I now use professional modeling
tools).
Also, the latest Poser 5 patch (SR 4.1) seems to fix some remaining issues
with the dynamic clothes.

$50 for UVMapper Pro. I think I've downloaded it before, but I've never
really done much with it. I'll have to try the demo again. $50 isn't so
bad, though. It would probably help to create realistic textures for the
dresses (or other clothes) that I might create.

I didn't realize there was a SR 4.1 patch.

For the record, I discovered that Wings3D does a good job of importing a 3DS
file and exporting a MDL file, suitable for hamapatch. In that way, I was
able to load the Penny model into Hamapatch in a very usable way, but it
took several minutes to export and import.
I also noticed that hamapatch doesn't work properly (most of the time) when
I change the "subdivision" value to anything other than 1 when exporting (it
flips normals and leaves out surfaces all over the place). That's
unfortunate. That, and it has a tendancy to crash often on my (WinXP)
machine. :-(
But even so, the relatively simple dress I'm designing seems to look fairly
good. I've learned so much since starting on it, that I almost wonder if I
shouldn't start it over, though.

You are voicing the same thoughts I had. I think it takes a lot of
practice; practice I don't have yet. The thing I learned after playing
around was to make sure the cloth was made up of irregular, chaotic,
small triangles instead of nice squares. It'll make the cloth fall better.
