Your light is one thing giving you so much render time. A 320x240 test (with no
AA) went from 4 minutes to 40 seconds (length of 1, and 1 Knight) with a light
fix: squares the light vectors to direction of travel, plus extra light in
array, wider falloff. (Is it just all those pieces lighting the board or some
other change?)


//vlen = 22.2
#declare _z_ = <3, 0, -3>-<-17, 10.4, 10.4>;
#declare _x_ = vnormalize(vcross(y,_z_))*15;
#declare _y_ = vnormalize(vcross(_z_,_x_))*15;

light_source { <-17, 10.4, 10.4> color rgb <1, 1, .8>
    adaptive 50
    spotlight
    radius 7
    falloff 40
    point_at <3, 0, -3>
  area_light _x_,_y_, 13,13 adaptive 0 jitter orient circular
    photons{
       reflection on
       refraction on
    }
}


Array length of 15 (same as orig) for another 20 seconds: total 1 minute versus
4 minutes.

This light gives 5-10 minutes per piece depending on the resolution and power
you have. Expect around 1/3 the render time or two thirds less.

Looks to me like, if you look at the Queen shadows in previous 2 imgs, a skewed
array = skewed shadows.

There is starting to appear more rays from the Knight hitting the board in this
lower res img (corner H5).
