That isn't MegaPOV specific, the dda_traversal warning.  Not as common a
thing to see as it used to be in earlier versions of POV-Ray.  I usually
encountered the problem with height fields when another object was being
intersected with them somehow.  Maybe someone remembers the fixes to that,
what I recall is just to move the camera a bit, but I think it could be more
the intersecting objects with meshes kind of thing.
