No limitation as such. In a
not-completely-accurate-but-close-enough-for-jazz nutshell, under the
right circumstances floating point accuracy limits can put "cracks" in
the triangulation of height fields. You get that message when a ray
hits a crack. You may or may not get visible artifacts. I know of no
real cure now, but sometimes slight alterations in camera placement
and/or viewpoint can help.
