VEEERY NICE :)

I would improve the texture of the ground to add much more realism to the
whole scene. But the nuts&bolts are amazing.

Congrats,

Okay, I'm increasing my score. That's gotta be a 9.5 for that material. At
least. I've seen things that look like that! Are those imperfections in the
model or in the material? They really make it look convincing.

Though I'm surpised it looks that good on these objects, since it's obviously
not the kind of metal they'd usually be made from. Still, it's enough for me to
judge that is looks right.

I'm not sure what to suggest to improve it. It looks a bit shiny and smooth,
which usually makes things look less realistic, but then there are metals that
really look like that and if you less smooth then you'll make it look like a
different material. So I guess my only suggestion would be to do several
different materials based on this, so you could make a red/orange version for
copper, a brown one for brass, etc.

It's a photo ???? no, it can't be a render, it's too realistic !!!!
Awesome !

   That's one of the most "AWESOME ROLEXS" I've seen to the date... :o

   I don't think the shiny finish is excessive. Perhaps not very usual 
for bolts, but I've seen metal finishes like this one. Indeed, your 
Wings3D skills are really good. Nothing to critize except perhaps the 
floor not being as realistic as the bolts, although it's very good anyhow.

Hi,

Thanks to all of you for your replies! The POV-Ray forum surely belongs to
the best places on the Internet because people here get the best treatment
along with great advices.

I will collect my reply in one post this time:

Indeed, the ground looks more like grey pancake. Next time I'll try
something else.

I can understand why you think it's a sky_sphere, but it's actually a
blueish area of light (both in terms of light_sources and in terms of an
object) to the right.

Blue gives the image a natural coldness in contrast to the area on the left
side, that is slightly red and warm. To obtain a more golden look, I could
change the blue light but I'd also loose the "natural coldness" element and
I don't think that should be necessary. I think (without having a sample of
gold nearby) that real gold has a higher diffuse value and is less
reflective, so it keeps more of it's own yellow color... Anyone please
correct me if I'm wrong.

Yes, imperfections are important. There are some imperfections in the model,
as you can see in the attached image. What probably can't be seen in the
attached image, are all the round edges. But there are no perfectly sharp
edges on these models. In concert with specular reflection this increases
realism and helps to define an objects shape. It's possible though, that I
went a little overboard with the soft edges, so the screws look melted.

That's a good idea and could help in finding the perfect material for
various purposes. I should do that - and hope they'll work in other
enviroments too, but this has not always worked in the past.

Oh, thanks! It's about a year ago now that I began with Wings3D and I was a
complete newbie to polygon modelling back then. I'm slowly improving and it
seems we're both going to benefit from this software. I originally had the
same problem as you regarding the interfaces of other modelling
applications. But Wings3D quickly becomes an extended part of ones hands.

Love these kind of responses.  :-)  Again, thanks to everyone for replying.
Next time I will render the scene with less noise and aliasing.

Regards,
Hugo

You're correct, but be careful not to make it too yellow. Gold tends to 
be more of a dull brownish-yellow than a bright yellow; if the pigment 
has too much saturation it will look fake.

One of these days I oughta whip up some generic metals and post them as 
an include file. I've had some success making credible metal textures, 
and the old metal.inc (or whatever it's called) is a bit outdated.

It's not just the soft edges, but the degree to which the screws are 
beaten up. If you were going for old, damaged screws, I would have 
expected sharper imperfections.. stripping, scratches, maybe a little 
pounding. And the finish would have been duller and maybe a bit dirty or 
tarnished. If you were going for new screws (as I assume), I would have 
make them less imperfect; real screws are usually pretty uniform, 
without all the little dents you've given them here. Tiny nicks and 
scratches or very subtle bumps (i.e. near-microscopic unevenness) would 
probably be more realistic. Subtle variations in texture might also be 
appropriate if, for instance, the screws were unevenly coated with 
something (perhaps to prevent corrosion?).

I believe the proper term for that is..

  *AWESOME ROLEX!*

  But then, maybee I'm just old..

are the imperfections carefully applied by hand ?
bo;t top dead center and the two vert below it
bottom one of the three even looks like someone slipped with a screwdriver

why do i get the feeling the nuts won't go the bolts ?
the threads in the nuts look more like a series of circles ???

having said that, i thought photo on the first image and still do
for the second, maybe in about 30yrs if i keep trying.......

Whoa! nice. Excellent modeled defects. The screws do look like they've
