Hi fellow POVers,

I'm working on the metallic material, but I think the result is worth
posting now. Maybe you can rate the photo-realism of it on a scale from 1-10
(10 being best) ?

The surroundings aren't too "warm", I know. It's grey and doesn't really fit
the motif... But it's a test... My original plan was also to make the blue
plastic into glass, but I haven't got that to work yet, and it will slow
down rendering. Rendering time for this image was 2 hours 20 minutes on AMD
1.4 GHz. (because I used focal blur with 80 samples)... I did not use
photons (doesn't seem to matter in this case) nor did I use radiosity. I did
the modelling in Wings3D.

Any comments are welcome.

Regards,
Hugo

All thumbs up! I'd give in an 8 on your scale (if 10 was perfect). I 
think this is mainly due to the pretty unrealistic background (as of 
composition, not the look of it).

Wow! Great job on lighting, textures and modelling. Can't wait to see 
the final :)

i'd give the metallic texture about a 9 or a high 8. however, it makes me
recalibrate the judging of my best metallic textures and places them around
3 or 4. overall for the image i'd give it an 8.

are the specular highlights caused by light or by a very bright white
object? so is it more a reflection of a white object, or a highlight?

The metal looks really good, though I'm not sure that's the same as being
realistic. Real metal often looks quite unremarkable and boring, which yours
certainly isn't!

I'd give it an 8 compared to the best renders and photos I've seen of metal, but
I think I might increase that score if you render it on a more familiar object
so I can judge more fairly (one thinks of Jaime Vives Piqueres' nuts & bolts as
a good example of a mundane object showing off a really good metal texture).

Hi Florian,

Thanks for the thumbs up! I agree with you, that the background doesn't
really suit the bottle and looks rather uncommon...

> Great job on lighting, textures and modelling.

Thanks for the encouragement!  :-)  I hope to improve it further, and to use
the flacon in a more complex scenery.

Regards,
Hugo

Hi Ross,

Thanks for rating my image so high.  :-)  The material consists of 2
textures, one which simulates metal and one which simulates dirt:

Texture 1 (metal):
   Plain yellow color, almost zero diffuse.
   Highly reflective; does not use variable reflection.
   Has a bump map to simulate "brushed metal" (I'm not sure how successful
that is yet)

Texture 2 (dirt):
   Plain white color, with slightly higher diffuse value than texture 1.
   Less reflective and uses variable reflection.
   Has no maps.

The two textures are then combined with a texture map, that tells where the
dirt is located, and how dirty it is.

It's a combination because I'm experimenting a little. But I think it's most
valid to say the specular highlights come from 2 bright objects, one to the
left and one behind (and above) the bottle.

Regards,
Hugo

Hi Tek,

Thanks for rating my image! It seems you all agree on the "8" and that's not
so bad, hehe... But I'd like to reach 10 of course... Well, your idea with a
"nuts and bolts" scene is good. I will try that.

Regards,
Hugo

Very nice. Looks like Wedgwood. The very bottom of the model is the only 
part IMO which you couldn't pass off as a photo.

The bottle fits exactly in the metal. Can I ask how you did that?

Sure. Maybe this can help you?
This is the unsmoothed, raw version.
