No, I think this looks just as good this way, maybe even better.  Making things
look shiny and new is easy, making them look old or worn or dirty or dusty is a
real challenge.

Yes, HDR has a huge effect on how scenes look, and not just with lighting.  For
reflective or shiny objects, its not so much that they reflect, but rather what
and how they reflect that makes them interesting.

Yes, I have in the past added objects in some scenes behind the camera etc to at
least give the appearance of this, usually just random shapes unless I had a
suitable model already. Just something to make the reflective surfaces a bit
different. Does not have anywhere near the effect of HDR but is better than just
reflecting a blank wall or empty sky.

IMHO this is looking really excellent. I can see no fault with it.

   Very nice modeling... proportions look perfect, with all the tiny
details at the correct scale. Lighting is very good too... I cannot see
any obvious artifacts. Texturing on the paint is also impressive, but
the rusty parts look like too reflective... I guess you didn't go for a
texture_map?

Thanks Thomas, it is alwasy easier to find the faults when you created the model
though. There are some not perfect joins on the glass (coincident surface at the
very top and where the sphere is connected to the cone the angle/join is not
perfect). However, I suppose often glass objects have these imperfections anyway
so maybe I meant to do it ;-)

Also, the object is not fully accurate, it was modelled from a photo and I could
not really see how the wire around the glass was connected up so I didn't
connect it to anything. Having found a few more photo's now I see that it is
connected to the bottom wire and this wire runs around (not through) the lamp
base.. I should fix this but am suffering from the 80:20 rule..

Hi Jaime,

Thanks, the model is CSG, my preferred method (really the only one I can do). It
does get tricky when you want to model an organic shape though (next I need to
try to add a tiger lily to the scene I am using this in which may be too much
for my CSG skills though..

Lighting is the building_probe or Overcast Breezeway, Soda Hall from
http://www.pauldebevec.com/Probes/

The texture consists of several layered textures in a texture map it is about
200 lines long so I will add a new post for this but it consist of 3 transparent
dirt textures (light/mid and very dirty). Then 3 textures one for paint one for
paint that is bubbling up a bit and one for rust.

I then created 3 copies of each of these textures one with each level of dirt
texture layered over it.

I then created 3 identical texture map with each one using the different levels
of dirt.

then I could use these texture maps in another texture map with a gradient to
transition from clean to dirty textures for each part of the lantern.

Apologies in advance for the complete lack of comments in my code (I always have
fun trying to go back and edit my old scenes..)

The texture is below, just realised I have missed out one of the light dirt
textures on the rust surface, will add that and reduce the reflection a bit on
the rust surface then do another render.

Ah yes! That is more obvious indeed. I wondered how the glass was lifted 
up with the bottom wire going through the base. I think there should be 
some kind of handle attached to it?

Otherwise, it is an excellent piece of modelling.

You are very good at this. I often use texture avatars from your Old
