Maybe it is the new normal calculation code, try adding "normal off" to
the isosurface. From the MacMegaPOV documentation:
"Technical notes on the function normal patch:
Apply accurate normal calculation to isosurfaces, parametrics, and
isoblobs by using the "normal" keyword (outside of a texture). This can
be followed by on/off, true/false, 1/0, etc. The default is to use
close approximation, the original method of choice for isosurfaces and
parametrics."
The documentation also mentions that it should probably be turned off
for functions using atan2 or noise3d.
