This is only a part of my never-really-started project for Povcomp. I
managed to find some free time to implement some ideas. I used Photoshop
to change tones and fix some little details.
Hope you like it. Comments and suggestions are welcomed.

I agree. Give that sucker a little bit of waxy feel. It is too much like a
matte plastic leaf, right now. Also, a littel bit of dewy/post rain water
would look nice, I think, but it really does look excellent. The cobbles
are beautiful.

It's a pity that you did'nt enter !
Maybe it could be better if the cobbles were worn and optionally wet,
because that makes me think more of a wall than a pavement.
Anyway, good job and very poetic ! love it !

Excellent!
One strange thing, though: some of the cobbles seem to merge (lower left;
upper middle). That is certainly not natural!

Realistically, the cobbles should be worn smoother than this as they've
had people/horses/wagons/cars/whatever on them for X years (and if
they're old enough, lots of rain). And as someone else pointed out, some
of the stones appear to be merging together. Other than that, they look
great.
That leaf could use some shine.

Thanks Jim.
The problem with the leaf is that I'm using a bicubic patch with an
image/bump map of the leaf on it, with alpha channel for transparency.
When I put some positive specular, the whole square patch shows up...
Therefore I think I need to make it look more decayed perhaps...

As I was telling Jim, the way I modeled the leaf does not let me put
some shiny finish on it, or the whole bicubic patch is visible...
Thanks for your comments :)

The cobbles are a 16-bit png heightfield, with a stone image map for
pigment and granite normal. Then there is a plane to change the color of
the "soil" between the cobbles. I tried to make it look like water, but
my results were not satisfactory... but I may still try later, perhaps
with HDR...
The leaf is a bicubic patch with an image/bump map with alpha channel.
I'm glad you liked it :)

Actually, in my original plan, I wanted to make puddles of water, but I
didn't like my first results. I'll try to continue playing with the
scene, but it's difficult to find free time!
I love cobbled streets, I'm happy that you liked it.

I know! Actually there were a few that I fixed by hand in the
heightfield... but it seems I overlooked a few :)
Perhaps I can fix it with Photoshop to avoid rerendering the scene :)
(~ 30 hours)

This is a new cobbled street! That's why it doesn't look eroded ;)
I'll try to improve the texture of the leaf and stones. Thanks for the
comments!

This is the version with less post-processing... perhaps the texture of
the leaf looks a bit better...
I'm amazed of how much the image changes between my two monitors. I'm
wondering how does it looks in your monitors...

Don't worry, it looks *very* nice. Love it ! But the leaf definitely has
a little disturbing something.
Very good work.

No you can do what you want you need to use the image_pattern with a b/w
profile or mask of the leaf as the image source. You make two
textures which duplicate the pigment and bump references but which
differ in finish and transparency.

With this level of JPEG compression, I'm hard pressed to tell this apart
from a photograph.

If I have one criticism it's that the cobbles appear to have a diagnoal
striation all aligned in the same direction.
I can't tell if it's deliberate or an artefact, but it shouldn't (IMHO) be
there.

I believe I'm doing what you're saying... the problem is that I can't
use neither reflection nor specular settings for the finish, as these
act on the whole patch, even those areas that are transparent... I don't
know if there is an easy workaround for this.
Or perhaps there is a way to give values to the specular using an image map?

You're a very perceptive person. I actually tried to diminish them with
postprocessing. In the unprocessed image, they are very noticeable. I
have to find the correct setting for the image map for the edges to be
not visible when tiling it.

Thanks for the compliment! The JPEG compression was set rather high, IIRC...

Hmmm Actually I could not reproduce your problem
I put runnable sdl and maps in p.b.scene-files
but the relevant sdl looked like this:
#local MyTex =
texture {
pigment {
image_map {
tga "im_oak.tga"
}
}
normal {
bump_map {
tga "bm_oak.tga" bump_size 4
}
}
finish {
diffuse .7
specular .5
roughness .1
reflection 0
}
}
bicubic_patch {
type 1
flatness 0.1
u_steps 3
v_steps 3
<0, 1, 3> <1, 1, 3> <2, 1, 3> <3, 1, 3>
<0, 1, 2> <1, 1, 2> <2, 1, 2> <3, 1, 2>
<0, 1, 1> <1, 1, 1> <2, 1, 1> <3, 1, 1>
<0, 1, 0> <1, 1, 0> <2, 1, 0> <3, 1, 0>
texture {
image_pattern {
tga "ip_oak.tga" use_alpha
}
texture_map {
[0
pigment { rgb 1 transmit 1 }
finish {
diffuse 0
specular 0
reflection 0
ambient 0
}
]
[1
MyTex
]
}
scale 3
rotate x*90
}

Perhaps rotating the leaf around the vertical axis a bit (and a bit about
one of the horizontal ones) will help. It seems now aligned with the
cobbles.
