It seems that I've come across the height-field related problem that
cause Megapov to loop indefinitely in some cases. In a picture I'm
working on, Megapov stops every 100 lines or so...
I know that Nathan has found a fix for it (see his message from Feb, 7
titled "Re:Height field Krach") , but is there a workaround for this in
the current version ? I've tried removing the light buffers (-UL), to no
avail. There are other alternate or even drastic solutions (like
removing the offending height-field...), but I'd rather go for a proven
one before spending time in testing !

Moving the height field or camera slightly (a small fraction of a unit)
might fix the problem, since it is caused by a floating-point precision
error.

The usual method, then :)
OK, I'll try that.
Thanks Nathan

If moving the camera doesn't work, you could try using an isosurface
with a pigment function instead of a height field.
