To prove the value of my chess library, I took the chess set I had created for
the Checkmate scene and added it to the chess_sets collection in the library so
it could be easily reused in other scenes.

I then created this scene where I used the existing chess set and created a
modified version of the black pawn to hold its defiant/taunting sign, and set it
as pawn #0 in the black chess set.  I then set up the board using the chess set
macros, added a custom placement macro to rotate the pieces to look at the
center of the board, and leaned the white queen backwards.

I used the collision library to help place the onlooker chess pieces around the
board as well.

The "ground" layer is just an isosurface box with granite texture bumps applied
to the surface.  There is a large sphere with an HDRI sky around the whole
scene, and a spotlight using LightSys components.  It was rendered with pretty
basic radiosity, a media sphere to add some fogginess, photons, and camera blur,
and took 7 1/2 hours to render on my laptop.

There is only about 1000 lines of new code, but a lot of that is comments and
boiler-plate scene template text, the rest is all reusable libraries.

Every time I see one of your chess scenes I think 'I should look up my old POV
chess code or make POV models of the old chess set I hand made and is store
away'.
 When I look at this scene I can't get over 7.5 hours render time and how I
would reduce it. The radiosity is needed, the media and photons not so much.
Media maybe, I haven't played with photons to much to know at a glance how much
it contributes to the scene. The one thing I know that blows up render time is
camera blur. I would probably do a post production blur. That should take a good
 chunk of time off your project.
 Other wise a nice scene, good job!
Have Fun!

For this one, camera blur is the definite culprit.  Without it, even with media
and photons turned on it takes a little over an hour.

I haven't done anything with tools to do post-production camera blur, so I rely
on what I can get from pov itself.  I like the way it gives me more photographic
rather than eye-realistic images, much as my hobby photography does.

Well done and +10 for the humor. :-)
