I am rendering a very simple scene, with a plane {y,0} and some
superellipsoid{} objects. If I have just one SE object, the scene renders
fine, if I have more than one, I get the error found here:

D:\pvf409\POVRay\myscenes\puzztest.pov:202: warning: Camera vectors are not
perpendicular. Making look_at the last statement may help.

Scene contains 3 frame level objects; 1 infinite.

Slab building error.
Cannot use non-perpendicular camera vectors with vista buffer.


Returned from renderer (non-zero return value)

-------------

My camera statement is

camera
{
 location < 0.0, 20.0,-20.0>
 look_at < 0.0, 0.0, 0.0>
 orthographic
 right 20*x
 up 20*y
}

I know the vectors are not perpendicular, but I need the vertical skew (it
makes each pov unit exactly 32x24 pixels on screen) for this project. Any
ideas?

Just make your camera vectors  perpendicular and the error will go away! I
get this with leveller scenes and have to adjust the camera specs to make it
work.

In this project, I need the camera vectors to be non-perpendicular. I need
the vertical skew - I need to look at the objects at a 45 degree angle, and
one pov unit needs to be exactly 32x24 pixels. The camera statement I
defined does just that.

Did you try to turn automatic bounding off?

Vista buffers, of course...
