This is probably too simple to be an IRTC entry, but I thought I'd share it.
It's a re-working of the archetypal rendered scene, in line with the current
IRTC topic. I left my chrome sphere outside too long and it corroded :)
This uses the same trick as in my animation: an isosurface with a couple of
pigment functions generating the rust. I might post the source at some point,
though I'm still working on this idea so it might turn into something much
better later on.
Questions? Comments?
Any suggestions on what I should do next with this scene?
Cheers,

The reflective bits are way too shiny for the level of corrosion
of the piece...try a dull metallic texture.

But it has to be shiny otherwise it's not a chrome sphere on a checkered plane!
;)
Though actually chrome can rust sort of like that, the chrome bits on my car (a
1970's MG) have spots of rust and shiny bits. Admittedly nothing quite as
corroded or shiny as that, so I take your point.

Tek, the rust colors seems to be too monochromatic.
Maybe you could let the rust colors vary from shades of brown
towards red, yellow and magenta.
Apart from the colors, I'm having a hard time convincing
myself that that metal would rust like that. Try to make it
look more like a kind of steel.

Yeah, it has a little variety but definitely not enough.

Well it's meant to look more like a chrome coating over some other metal. It's
adapted from the animation I posted to p.b.a which showed a painted ball
rusting, so the rust looks like it starts under the surface of the metal and
then breaks through, which isn't how it should rust. I hadn't really thought
much about that, I just changed the paint material to be chrome! :)
Good suggestions, thank you.

Looks good, but more like melting plastic coating than corrosion IMHO.
And the checkered plane badly needs +a0.0 +am2 :-)

Great work. I look forward to see any improvements, but it's great IMHO as
it stands now.

That's up to you, you are the artist... but if I may suggest something, let
your imagination run wild - there's a lot of premise in your techniques.

It is quite possible to have clean shiny chrome and rust too. You have it
right, that is what a bad plating job looks like. If the metal was corroded
before the plating was applied, and the corrosion was not completely cleaned
or removed first, then the plating will not bond correctly, and the rust
will start from under the surface.
For the IRTC, just extend the decay; corrode the plane too, eat away one
corner of the image itself and submit it as a decay(ed) entry... ;-)

Cool idea! And thanks for explaining how metal can corrode like that, I think I
understand now why bits of my car look that way!
