Wow, now I understand why the first was a WIP!
Great textures.

Last update for the moment... until I find some interesting situation for a
real scene with it.

The dents where done in Wings3d, using the random point selection to select
10% of the points, then moving them along the normal: one time to the inside
and another to the outside. Both pics use the same technique, but 9c has
more depth on the dents.

Regards,

   I'm already on 0.99.04, but thanks for the tips...

   You can also use Poseray... it does a better job, specially on how it
handles the textures, but in general you have much more control on the
exported code.

   Then better don't look at the new version... :)

   No, I didn't think at all about animating it, but in this case it will be
very easy to animate it in POV-Ray, just exporting the arms as a separate
mesh and using some simple transformations.

   Now I don't know what you're talking about... marker lights? You mean
placing lights to use the points later, or something like that?

Very nice job, as usual, Jaime! I really like the dents, chipped paint, and
heavy rust, as well as the great (I'm assuming) proceduralized textures.

I'd maybe add a big dent in one or more corner(s) of the head box where some
careless child has dropped him many times (as they tend to do, especially when
battling Jedi knights or clone troopers or Klingons or...)

Cheers,
Rob :)

It looks like an honest-to-goodness photo.  Just perfect.

IMO, the family dog just dug it up in the backyard; it was lost in the bushes
decades ago by mistake, and sadly forgotten by its young owner. Now, as an
older adult, the owner cherishes it for the wonderful memories it evokes. (And
he gave his dog a nice meaty bone as a reward for finding it!)

Sorry, yes, using lights and the 'position highlight' command to mark points of
rotation.  For a very simple model, one can often align the axis of rotation
with one of the cardinal axes and export that way, but for a very complex
object or an object that will incorporate POV-ray primitives, it can be very
helpful to know where a given point or shape is.

As Wings doesn't have a way to export a point or line primitive, I tend to use
light sources.

   Ah... clever! I also wanted sometimes to export points (not for animation,
but to place other objects on the surface), but never figured out this
one... thanks!

   Thanks, but in this case I didn't use any procedural pattern, so I don't
know if that counts as proceduralizing... ;) ...I just used the material map
feature to mix the uv maps with a photo of rusted metal, something like:

   texture{
    uv_mapping
    material_map{
     png "rust_map" // b&w (2 indexes) image generated from the one below
     texture{pigment{image_map{jpeg "any_rust_photo.jpg"}}}
     texture{pigment{image_map{png "uv_map.png"}}}
    }
   }

   I think I prefer Kenneth story on the post bellow: it doesn't involves any
further damage to the poor little robot... :)

   Beautiful story... thanks for coming up with such nice explanation for the
excess of rust and lack of real damage. :)

Jaime, this is beautiful. One of my favourite rendered images ever.
