Ok,

this scene is a test play to get stone have a weathered look. The grass
still needs much work, but it's there just because I needed _some_
background. All the other textures need still some work too, but that's
something I'm working on right now. I am quite satisfied for the cracks
and the modelling of the column. The colors right now are a bit
comic-like, but much better comparing to being just too plain. According
to photos, for example the ancient roman columns are not so white
today... <http://data.GreatBuildings.com/gbc/images/cid_967337.jpg>.

If I manage to get these done in time, they will end up to my IRTC
entry. I am quite badly out of any spare time, tough, so I think I will
not make it.

This scene was inspired by Petri Hiltunen's fantasy world Borvaria,
which has been setting for some of his comic books and strips this far
and is right now out as role playing game named Praedor. Unfortunately
it's all in finnish, but you can have a look at example strip at
<http://www.magus-lehti.com/galleria/Praedor.htm>.

The column is completely modelled as ISO surfaces made by hand, and the
grass is smooth polygon mesh made with a little Java program. As you can
see, some of the cracks in the column are "real" and some of them are
just normal surface tricks. I am trying to figure out whether the real
ones are really worth the enormous tracing time, but so it seems.

Don't know why you'd think the colors are comic-like.  It has a nice
photo-realistic appearance to me.
I can't tell what you mean by cracks in that... chipping maybe?

Yes, that. Being non-native english spea... writer, my vocabulary is not
too broad when it comes to non-techie stuff :-). Thanks.

I like it, but 8 hours for isosurface with radiosity is not that slow.  

It looks a bit more like plaster(?) rather than stone, but the moss is
nice.  The grass looks a bit regular.  

Maybe some additional roughness for the surface of both moss and stone
would be good, but of couse that would slow down things

Didn't read your message but looked at the image, it's
fantastic, but who's been out with a hair brush and 
brushed the grass so that it's all sticking up like that.

The column is excelent.

Yeah, in fact the look of the column I was aiming at is stone covered
with plaster, but the plaster is chipping and stone becomes visible. I
wanted to recreate the look the ancient roman buildings have right now,
not being so sure what the exact materials were... I think I should read
history a bit.

Thanks for ideas - I will try out. I have mostly tried to add roughness
by means of textures, because adding yet another layers of textures to
ISO surface would slow down the rendering once more, but let's see.
