This is a render of version 2 of my metallic paint. It's an advancement of the
system I used for the animation on p.b.a. It still has an underlying metallic
layer with a gloss layer on top, but it also has adjustable noise in the
metallic layer, and a glitter layer.
The source is on p.b.s-f (as a reply to the metallic paint thread), in case
anyone has some objects that would look good in metallic paint.
I think it looks pretty realistic, but do you have any suggestions on how I
could improve it?

I've worked in a big paint shop where they only painted color tests on
paper for a given Car company...
Anyway, I've seen cars, and I've seen fresh car paint...
This really look realistic, though I would give a much much more fine
noise or graininess, and the noise should go darker and lighter also...
(more contrast)
This is probably because there is a layer beneath the paint that is
silver and is noisy...
Anway, nice work!

Yes it's very nice. Have you tried with radiosity and HDR lighting, because
you'll need it sooner or later? Even if you spend a lot of time, fine-tuning
the texture for simple lighting, you may have to do it again, when you
change the light. That's just my experience. :o) Also, based on the glance
I had at your files, I see that you're not using gamma correction. This may
be a deliberate choice, otherwise ...mm.. it will change some things again.
Let me know if you have questions.. I'll try to help.

Hugo

It works fine with radiosity, because it gets it's ambient brightness from
the #default statement so I can just switch on/off ambient lighting without
modifying the material itself :) However it does require a light source in
the scene, because it uses specular highlights to get the metallic and
glitter efffects.
Besides which it all works based on the pigment you give it, so a lot of
tuning (particularly brightness for gamma, radiosity, HDR) can be done using
the colour and light sources in the scene it's being used in.
But now you mention it I've been meaning to try a scene using HDR, and I
think I'll use this texture in my first test :)

Well, as with all grain effects, the anti-aliasing and focal blur will alter
the appearance of the grain if it's very fine. I chose the size of grain so
that it gives the right impression without being so small that it's just
random noise, but obviously it can be scaled to suit the situation.
> and the noise should go darker and lighter also... (more contrast)
This is one of the options in the metallic macro, I prefer this low-noise
setting but I confess that's more based on taste than on reference material
:)

I was just about to post a request for this very thing... Looks like someone
has already worked out how to do it... and very convincing it is too!
Cool :-)

Wow, that looks nice!
I can't think of any way you could improve this, it looks very accurate.
perhaps you could use ifndef to automaticly set things like color or the
#default statment if the user forgets to, but these are issues about usage.
The effect works brilliently.

It looks cool on smoothly shaded pigments too, so I might try an airbrush-style
image :)

Here's a version with radiosity and HDR. Like I said the metallic effect
requires a light source, so this needed a bit of tweaking to make the light
source match up to roughly the position of the sun in the HDR image without
interfering too much with the radiosity. I also turned off the sharp specular
highlight that was on the gloss coating 'cause it's not needed with such a
realistic reflection image.
Basically it looks good if most of your lighting comes from light sources, if it
doesn't then you'll need to mess around creating some lights just for this
object. But that's what I did here and I think it's worth the effort.
And while we're on the subject, does anyone know if it's theoretically possible
to get specular radiosity interaction? I know pov can't do it, but as far as I
can see it should be possible to do a specular calculation on the radisoity
samples. It would be slow but still much better than true blurred reflections.

You've got... lets see... Red, White, Cream/gold and Green.... but where's
black?
I mean really! Who would buy anything other than a cool black vehicle!?!
Just think of Kitt.
Hmm I wonder if there is a POV model of Kitt floating around on the web.

You do realise metallic black is a contradiction? Well nearly, it would still
glitter but it would lose the illumination properties which are the whole reason
I started this!

I agree, black cars are way cooler than red or green ones.

I take it back, metallic black looks cool! Like I said it's just the reflection
and the glitter, but it looks much better than I thought it would.
Though I still don't recall ever seeing a metallic black car.

Apparently not. Looking round the office car park I can see lots of metallic
cars, red, silver, about a dozen different greens, but no metallic black.
...Actually I can't see any black cars here! Maybe it's unpopular with my
colleagues. I'm sure you're right, I just prefer black cars that aren't
metallic, like Kitt :)

I was going to answer you, that black metallic can't be done, but BWM
does indeed have a Carbon Black Metallic. I found a picture of it at
http://www.bmwworld.com/pics/3er/e46/m3/6074_1024.jpg
The metallic effect is not obvious, but that may be due to poor picture
quality.

I can see it, just look near the highlight, there's a large blue/green metallic
highlight. Which actually means it's a very dark blue/green, not black! :)

It is black, photgraph is of a very low quality, so the colors may look a

I've made some pictures of black audi's last winter. The cars were parked
just a few meters away from were the bus stopped, and I could not resist the
temptation of making pictures.
I know the quality is realy bad, but at least it are (metallic) black cars.
