I wish I still had mine. :-( It was ... STABLE. And a workhorse. But the stupid

Obviously not, at least not with POV-Ray for Windows... I used a 16-bit
PNG generated with Wilbur to be parsed to a spherical mesh2 with this
script:

#include "functions.inc"
#declare xx=1024;

#declare minrad=22;

}
#declare vertices=2+xx*(yy-2);
#fopen asteroid_mesh_inc "asteroid_mesh.inc" write
#write (asteroid_mesh_inc,

#declare a=1;
#while (a<yy-1)
#declare b=0;
// #declare rdcum = 0;
#while (b<xx)
#declare redval=eval_pigment(AsteroidRelief, <(0.5+b)*(1/xx),
(0.5+a)*(1/yy), 0>).red * (maxrad-minrad);
#declare greenval=eval_pigment(AsteroidRelief, <(0.5+b)*(1/xx),
(0.5+a)*(1/yy), 0>).green * ((maxrad-minrad)/255);
#declare rd=minrad+redval+greenval;
/* #if (a=1 | a=yy-2)
#declare rdcum=rdcum+rd;
#end */
#write (asteroid_mesh_inc,

#end

#end
#write (asteroid_mesh_inc, " }\n}")
#fclose asteroid_mesh_inc
// end of code
It seemed to parse correctly - but POV-Ray crashed immediately
afterwards, regardless how big or small values I used for xx and yy. I
didn't try yet whether it still produced a valid mesh2 - but I don't
think so.
See you in Khyberspace!

/Some/ day I'll teach you folks to specify the version number when
reporting an issue ;)

If the scene parses, it's not an issue with `eval_pigment()`, as that's
called during parsing. Rather, the /scene/ created must have some
problematic properties.
Also, that's a TGA file you're using there, not PNG ;)
To further diagnose the issue, I'd probably need a copy of the image.

That's a bit subtle, for us.
Just say what you mean before we grow beards. ;)

If you don't provide the version number, there is no way to know if the
issue is an old one, maybe already fixed in later version, or a new one
accidentally introduced.
Where you using version 3.5, 3.6, 3.7, the latest test build...?

"Ich verlange ordentliche Meldungen, verdammt nochmal!" is the quote of
the day for Yadgar.
As for you Tommies, ask the folks at Bletchley Park to deciper it :P

So you have said. But you missed that little word that every good boy
uses. "Please!"
Now is that so hard? :P
