I've noticed that when I use +MB0 the bounding threshold is still set to 1.
Is it possible to set it to zero? Reason is that I have an animation with no
objects in the 1st frame. Seems that POV doesn't switch bounding on in any
of the subsequent frames, causing it to render much slower.
Of course I can fudge it by placing an unseen object in the 1st frame, but
this is psychologically disconcerting.

Thanks
M.E.

  That doesn't sound like a desirable nor intended behaviour. It might
be a bug worth reporting.

While not nice, this is indeed intended behavior in POV-Ray 3.6.x and 
earlier due to setup work being done once.  The solution is to have at least 
one object in the first frame.

This no longer is an issue in POV-Ray 3.7 (beta).
